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.
