s Power Density up to 0.85W/cm 3s 5V & 12V Input

s 5V, 9V, 12V and 15V Output s Footprint from 1.17cm 2s UL 94V-0 Package Material s No Heatsink Required s Internal SMD Construction s Toroidal Magnetics s Fully Encapsulated

s No External Components Required s MTTF up to 2.1 Million hours s Custom Solutions Available s No Electrolytic or Tantalum Capacitors DESCRIPTION

The NMA series of industrial temperature range DC-DC converters are the standard building blocks for on-board distributed power systems. They are ideally suited for 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 1watt.

When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up.
