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. The wide
temperature range guarantees startup from –40°C
and full 1 watt output at 85°C. For lower ripple,
refer to output ripple reduction section.

1. Calculated using MIL-HDBK-217F with nominal input voltage at full load.
2. See derating curve.
3. Supply voltage must be disconnected at the end of the short circuit duration.
All specifications typical at TA=25°C, nominal input voltage and rated output current unless otherwise specified.
