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.

2. Supply voltage must be disconnected at the end of the short circuit duration.

FEATURES

DESCRIPTION

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.
