The LME series of DC/DC converters are optimised
for low-power operation. They are ideally suited to
generating a negative supply where only a posi-
tive rail exists.

When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external ca-
pacitance 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.

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.
