DESCRIPTION
The NMA series of DC-DC converters are the
standard building blocks for on-board
distributed power systems. They are ideally
suited to providing dual rail supplies on
primarily digital boards with the added
benefit 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.
