DESCRIPTION
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.
