■ Pin Compatible with LME
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.

DESCRIPTION
INPUT CHARACTERISTICS
The NME Series of DC-DC Converters is
particularly suited to isolating and/or
converting DC power rails. The galvanic
isolation allows the device to be configured
to provide an isolated negative rail in systems
where only positive rails exist.
