DESCRIPTION
1. Calculated using MIL-HDBK-217FN2 calculation model with nominal input voltage at full load.
All specifications typical at T =25°C, nominal input voltage and rated output current unless otherwise specified.
A
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 1 watt.
