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
Voltage Set Point Accuracy See tolerance envelope
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 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.
