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

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.
