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.

The NMXU series of DC/DC converters is par-
ticularly suited to isolating and/or converting DC
power rails. The galvanic isolation allows the
device to be configured to provide an isolated
negative rail in systems where only positive rails
exist. The devices are particularly suited for use
in distributed power systems where there is low
variation in the bus voltage levels.

1. Calculated using MIL-HDBK-ꢀ17F with nominal input voltage at full load.
ꢀ. Supply voltage must be disconnected at the end of the short circuit duration.
All specifications typical at TA=ꢀ5°C, nominal input voltage and rated output current unless otherwise specified.
