They are ideally suited to providing dual rail supplies on primarily digital boards with the added benefit of galvanic isolation to reduce switching noise. All of the rated power may be drawn from a single pin provided the total load does not exceed 1 Watt. 1 2 4 VIN GND 5 6 --V 0V +V DC-DC Converters 2-15 NMA SERIES Isolated 1W Dual output absolute maximum ratings over operating free air* temperature range Input voltage VIN NMA03 types . . . . . . . . . . . . . . . . . . . . . . . . . . 5V Input voltage VIN NMA24 types . . . . . . . . .
