DESCRIPTION
The NMD series of DC-DC converters are
ideally suited to applications where a
potential difference exists between loads, eg
motor control circuits. The twin outputs offer
cost and space savings by consolidating two
DC-DC Converters into one package. All of
the rated power may be drawn from a single
output 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.
