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.

DESCRIPTION
The NMXSO series of DC/DC converters is
particularly suited to isolating and/or converting
DC power rails. The galvanic isolation allows the
device to be congured 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.
