(1) Maximum power dissipation is a function of TJ(max),qJA and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD= [TJ(max) – TA] /qJA.
(2) This thermal data is measured with high-K board (4 layers board according to JESD51-7 JEDEC standard).

DETAILED DESCRIPTION
The TPS6223X synchronous step down converter family includes a unique hysteretic PWM controller scheme
which enables switch frequencies over 3MHz, excellent transient and AC load regulation as well as operation
with cost competitive external components.
The controller topology supports forced PWM Mode as well as Power Save Mode operation. Power Save Mode
operation reduces the quiescent current consumption down to 22mA and ensures high conversion efficiency at
light loads by skipping switch pulses. In forced PWM Mode, the device operates on a quasi fixed frequency,
avoids pulse skipping, and allows filtering of the switch noise by external filter components.
The TPS6223X devices offer fixed output voltage options featuring smallest solution size by using only three
external components.
The internal switch current limit of typical 850mA supports output currents of up to 500mA, depending on the
operating condition.
A significant advantage of TPS6223X compared to other hysteretic PWM controller topologies is its excellent DC
and AC load regulation capability in combination with low output voltage ripple over the entire load range which
makes this part well suited for audio and RF applications.
OPERATION
Once the output voltage falls below the threshold of the error comparator, a switch pulse is initiated, and the high
side switch is turned on. It remains turned on until a minimum on time of tONmin expires and the output voltage
trips the threshold of the error comparator or the inductor current reaches the high side switch current limit. Once
the high side switch turns off, the low side switch rectifier is turned on and the inductor current ramps down until
the high side switch turns on again or the inductor current reaches zero.
In forced PWM Mode operation, negative inductor current is allowed to enable continuous conduction mode even
at no load condition.
POWER SAVE MODE
Connecting the MODE pin to GND enables the automatic PWM and power-save mode operation. The converter
operates in quasi fixed frequency PWM mode at moderate to heavy loads and in the PFM (Pulse Frequency
Modulation) mode during light loads, which maintains high efficiency over a wide load current range. In PFM
Mode, the device starts to skip switch pulses and generates only single pulses with an on time of tONmin. The
PFM Mode frequency depends on the load current and the external inductor and output capacitor values. The
PFM Mode of TPS6223X is optimized for low output voltage ripple if small external components are used. Even
at low output currents, the PFM frequency is above the audible noise spectrum and makes this operation mode
suitable for audio applications.
The on time tONmin can be estimated to:
(1)
Therefore, the peak inductor current in PFM mode is approximately:
(2)
The transition from PFM into PWM mode and vice versa can be estimated to:
(3)

SLVS941E –APRIL 2009–REVISED DECEMBER 2010
FORCED PWM MODE
Pulling the MODE pin high forces the converter to operate in a continuous conduction PWM mode even at light
load currents. The advantage is that the converter operates with a quasi fixed frequency that allows simple
filtering of the switching frequency for noise-sensitive applications. In this mode, the efficiency is lower compared
to the power-save mode during light loads.
For additional flexibility, it is possible to switch from power-save mode to forced PWM mode during operation.
This allows efficient power management by adjusting the operation of the converter to the specific system
requirements.
100% DUTY CYCLE LOW DROPOUT OPERATION
The device starts to enter 100% duty cycle mode once the input voltage comes close to the nominal output
voltage. In order to maintain the output voltage, the High Side switch is turned on 100% for one or more cycles.
With further decreasing VIN the High Side MOSFET switch is turned on completely. In this case the converter
offers a low input-to-output voltage difference. This is particularly useful in battery-powered applications to
achieve longest operation time by taking full advantage of the whole battery voltage range.
The minimum input voltage to maintain regulation depends on the load current and output voltage, and can be
calculated as:
(4)
With:
IOUTmax = maximum output current plus inductor ripple current
RDS(on)max = maximum P-channel switch RDSon.
RL= DC resistance of the inductor
VOUTmax = nominal output voltage plus maximum output voltage tolerance
UNDER VOLTAGE LOCKOUT
The under voltage lockout circuit prevents the device from misoperation at low input voltages. It prevents the
converter from turning on the switch or rectifier MOSFET under undefined conditions. The TPS6223X devices
have a UVLO threshold set to 1.8V (typical). Fully functional operation is permitted for input voltage down to the
falling UVLO threshold level. The converter starts operation again once the input voltage trips the rising UVLO
threshold level.
SOFT START
The TPS6223X has an internal soft-start circuit that controls the ramp up of the output voltage and limits the
inrush current during start-up. This limits input voltage drops when a battery or a high-impedance power source
is connected to the input of the converter.
The soft-start system generates a monotonic ramp up of the output voltage and reaches the nominal output
voltage typically 100ms after EN pin was pulled high.
Should the output voltage not have reached its target value by this time, such as in the case of heavy load, the
converter then operates in a current limit mode set by its switch current limits.
TPS6223X is able to start into a pre-biased output capacitor. The converter starts with the applied bias voltage
and ramps the output voltage to its nominal value.
ENABLE / SHUTDOWN
The device starts operation when EN is set high and starts up with the soft start as previously described. For
proper operation, the EN pin must be terminated and must not be left floating.
Pulling the EN pin low forces the device into shutdown, with a shutdown quiescent current of typically 0.1mA. In
this mode, the P and N-channel MOSFETs are turned off, the internal resistor feedback divider is disconnected,
and the entire internal-control circuitry is switched off.

The EN input can be used to control power sequencing in a system with various DC/DC converters. The EN pin
can be connected to the output of another converter, to drive the EN pin high and getting a sequencing of supply
rails.
SHORT-CIRCUIT PROTECTION
The TPS6223X integrates a High Side and Low Side MOSFET current limit to protect the device against heavy
load or short circuit. The current in the switches is monitored by current limit comparators. When the current in
the P-channel MOSFET reaches its current limit, the P-channel MOSFET is turned off and the N-channel
MOSFET is turned on to ramp down the current in the inductor. The High Side MOSFET switch can only turn on
again, once the current in the Low Side MOSFET switch has decreased below the threshold of its current limit
comparator.
THERMAL SHUTDOWN
As soon as the junction temperature, TJ, exceeds 150°C (typical) the device goes into thermal shutdown. In this
mode, the High Side and Low Side MOSFETs are turned-off. The device continues its operation when the
junction temperature falls below the thermal shutdown hysteresis.

OUTPUT FILTER DESIGN (INDUCTOR AND OUTPUT CAPACITOR)
The TPS6223X is optimized to operate with effective inductance values in the range of 0.7mH to 4.3mH and with
effective output capacitance in the range of 2.0mF to 15mF. The internal compensation is optimized to operate
with an output filter of L = 1.0mH/2.2mH and COUT = 4.7mF. Larger or smaller inductor/capacitor values can be
used to optimize the performance of the device for specific operation conditions. For more details, see the
CHECKING LOOP STABILITY section.
INDUCTOR SELECTION
The inductor value affects its peak-to-peak ripple current, the PWM-to-PFM transition point, the output voltage
ripple and the efficiency. The selected inductor has to be rated for its dc resistance and saturation current. The
inductor ripple current (ΔIL) decreases with higher inductance and increases with higher VI N or VO UT.Equation 5
calculates the maximum inductor current under static load conditions. The saturation current of the inductor
should be rated higher than the maximum inductor current as calculated with Equation 6. This is recommended
because during heavy load transient the inductor current will rise above the calculated value.

In high-frequency converter applications, the efficiency is essentially affected by the inductor AC resistance (i.e.,
quality factor) and to a smaller extent by the inductor DCR value. To achieve high efficiency operation, care
should be taken in selecting inductors featuring a quality factor above 25 at the switching frequency. Increasing
the inductor value produces lower RMS currents, but degrades transient response. For a given physical inductor
size, increased inductance usually results in an inductor with lower saturation current.
The total losses of the coil consist of both the losses in the DC resistance, R(DC), and the following
frequency-dependent components:
• The losses in the core material (magnetic hysteresis loss, especially at high switching frequencies)
• Additional losses in the conductor from the skin effect (current displacement at high frequencies)
• Magnetic field losses of the neighboring windings (proximity effect)
• Radiation losses
The following inductor series from different suppliers have been used with the TPS6223X converters.

OUTPUT CAPACITOR SELECTION
The unique hysteretic PWM control scheme of the TPS62230 allows the use of tiny ceramic capacitors. Ceramic
capacitors with low ESR values have the lowest output voltage ripple and are recommended. The output
capacitor requires either an X7R or X5R dielectric. Y5V and Z5U dielectric capacitors, aside from their wide
variation in capacitance over temperature, become resistive at high frequencies.
At light load currents the converter operate in Power Save Mode and the output voltage ripple is dependent on
the output capacitor value and the PFM peak inductor current. Higher output capacitor values minimize the
voltage ripple in PFM Mode and tighten DC output accuracy in PFM Mode.
INPUT CAPACITOR SELECTION
Because of the nature of the buck converter having a pulsating input current, a low ESR input capacitor is
required for best input voltage filtering and minimizing the interference with other circuits caused by high input
voltage spikes. For most applications a 2.2mF to 4.7mF ceramic capacitor is recommended. The input capacitor
can be increased without any limit for better input voltage filtering. Because ceramic capacitor loses up to 80% of
its initial capacitance at 5V, it is recommended to use 4.7mF input capacitors for input voltages > 4.5V.
Take care when using only small ceramic input capacitors. When a ceramic capacitor is used at the input and the
power is being supplied through long wires, such as from a wall adapter, a load step at the output or VIN step on
the input can induce ringing at the VIN pin. This ringing can couple to the output and be mistaken as loop
instability or could even damage the part by exceeding the maximum ratings.
Table 2 shows a list of tested input/output capacitors.

CHECKING LOOP STABILITY
The first step of circuit and stability evaluation is to look from a steady-state perspective at the following signals:
• Switching node, SW
• Inductor current, IL
• Output ripple voltage, VOUT(AC)
These are the basic signals that need to be measured when evaluating a switching converter. When the
switching waveform shows large duty cycle jitter or the output voltage or inductor current shows oscillations, the
regulation loop may be unstable. This is often a result of board layout and/or L-C combination.
As a next step in the evaluation of the regulation loop, the load transient response is tested. The time between
the application of the load transient and the turn on of the P-channel MOSFET, the output capacitor must supply
all of the current required by the load. VOUT immediately shifts by an amount equal to ΔI(LOAD) x ESR, where ESR
is the effective series resistance of COUT.ΔI(LOAD) begins to charge or discharge COgenerating a feedback error
signal used by the regulator to return VOUT to its steady-state value. The results are most easily interpreted when
the device operates in PWM mode.
During this recovery time, VOUT can be monitored for settling time, overshoot or ringing that helps judge the
converter’s stability. Without any ringing, the loop has usually more than 45° of phase margin.
Because the damping factor of the circuitry is directly related to several resistive parameters (e.g., MOSFET
rDS(on)) that are temperature dependant, the loop stability analysis has to be done over the input voltage range,
load current range, and temperature range.
LAYOUT CONSIDERATIONS
As for all switching power supplies, the layout is an important step in the design. Proper function of the device
demands careful attention to PCB layout. Care must be taken in board layout to get the specified performance. If
the layout is not carefully done, the regulator could show poor line and/or load regulation, stability issues as well
as EMI problems. It is critical to provide a low inductance, impedance ground path. Therefore, use wide and
short traces for the main current paths. The input capacitor should be placed as close as possible to the IC pins
as well as the inductor and output capacitor.
Use a common Power GND node and a different node for the Signal GND to minimize the effects of ground
noise. Keep the common path to the GND PIN, which returns the small signal components and the high current
of the output capacitors as short as possible to avoid ground noise. The FB line should be connected to the
output capacitor and routed away from noisy components and traces (e.g. SW line).

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time
of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such
components to meet such requirements.
