The devices are fully compatible with CECC00802 to 280C which allows them to be placed and reflowed with IC's, thus reducing time and cost in production. The co-planarity of the pin positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged NA - Not available for electrical connection PRELIMINARY Notice : This is not a final specification.

The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. 1 Calculated using MIL-HDBK-217F with nominal input voltage at full load. 4 NTA SERIES Isolated 1W Dual Output SM DC-DC Converters typical characteristics1 NTA05 series 80 0512/0515 60 Efficiency % % Deviation from Nominal 25 0505 0509 40 20 0 0 20 40 80 60 20 15 10 5 0512 0 -5 0505 -10 100 0509 0515 0 20 % of Total Output Current 40 80 60 100 % of Total Output Current NTA12 series 25 1212/1215 60 Efficiency % % Deviation from Nominal 80 1209 1205 40 20 0 0 20 40 80 60 20 15 0 1215 -5 0 % of Total Output Current 40 80 60 100 2.0 e +2.5% Output Voltage -2.5% -7.5% Output Power (W) Typical Load Lin 1.5 85 1.0 0.5 Safe Operating Area 10 50 Output Load Current (%) 1 20 temperature derating graph +10% V nominal 1212 % of Total Output Current tolerance envelope +5% 1205 5 -10 100 1209 10 100 0 -40 0 50 100 150 Ambient Temperature (C) All data taken at TA=25C NTA SERIES 5 NTA SERIES Isolated 1W Dual Output SM DC-DC Converters typical characteristics efficiency versus load - temperature surface 80 70-80 60-70 50-60 40-50 30-40 20-30 10-20 0-10 60 20 40 60 80 20 100 Efficiency (%) 40 -20 Temperature (C) -40 100 80 60 40 20 0.5 0 0 Load (%) output voltage versus load - temperature surface 17.6-18.1 17.1-17.6 16.6-17.1 16.1-16.6 15.6-16.1 15.1-15.6 14.6-15.1 14.1-14.6 13.6-14.1 18.1 17.6 17.1 16.1 15.1 40 60 14.6 20 14.1 6 -20 100 60 80 -40 Load (%) 40 20 0.5 0 13.6 Temperature (C) 100 15.6 80 Positive Vout (V) 16.6 NTA SERIES Isolated 1W Dual Output SM DC-DC Converters outline dimensions1 18 Pin SMD package style 15.24 DETAIL A 10.16 18 11.20 10.40 10 NTA0505M 7.70 REFERENCE PLANE YYWW P 1 9 2.54 0.65 0.55 0.95 0.55 10 PINS 0.2 4 10 PINS S 0.2 S 2.10 6.60 (5.95) (6.35) 5.85 DETAIL A S 0.25 0.10 10 PINS 0.2 S 2.79 MAX 0.50 (1.875 MAX) SEATING PLANE 0.30 0.20 recommended footprint details 10.16 1.75 10.80 2.54 1 1.00 MIN All pins on a 2.54mm pitch.
