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.

SIP

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.
