DESCRIPTION
The LME series of DC-DC converters are
optimised for low-power operation. Due to
the low quiescent current they are able to
offer efficiencies up to 75%. The use of
advanced magnetics ensures a minimal
quiescent current of around 2.5mA which
ensures that efficiency is maximised in low
power applications. They are ideally suited
to generating a negative supply where only
a positive rail exists.

i When operated without additional external load capacitance, the output voltage of the devices is guaranteed
to be within 95% of its steady state value within 100ms after the input voltage has reached 95% of its steady
state value, irrespective of the rise time of the input voltage.
ii 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.
