FEATURES
DESCRIPTION
The NMA series of DC/DC converters are the
standard buliding blocks for on-board distrib-
uted power systems. They are ideally suited for
providing dual rail supplies on primarily digital
boards with the added benefi t 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.

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.
