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.

1 Calculated using MIL-HDBK-217F with nominal input voltage at full load.

2 See derating curve

3 Supply voltage must be discontinued at the end of the short circuit duration.

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.
