Description

The LME0305D 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.
