The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up. ■ No Heatsink Required ■ Internal SMD Construction INPUT CHARACTERISTICS ■ Toroidal Magnetics Parameter ■ Fully Encapsulated ■ No External Components Required ■ MTTF up to 2.1 Million hours ■ Custom Solutions Available ■ 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.
