DESCRIPTION
ABSOLUTE MAXIMUM RATINGS
The NMA series of industrial temperature range
Lead temperature 1.5mm from case for 10 seconds 260C
DC/DC converters are the standard building blocks
Input voltage VIN, NMA05 types 7V
for on-board distributed power systems. They are
Input voltage VIN, NMA12 types 15V
ideally suited for providing dual rail supplies on
Input voltage VIN, NMA15 types 18V
primarily digital boards with the added benet 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. Calculated using MIL-HDBK-217FN2 calculation model with nominal input voltage at full load.
All specications typical at TA=25C, nominal input voltage and rated output current unless otherwise specied.

The voltage tolerance envelope shows typical load regulation characteristics for this
product series. The tolerance envelope is the maximum output voltage variation due to
changes in output loading.
