LM2758 Datasheet (National Semiconductor) - Switched Capacitor Flash LED Driver

LM2758, Switched Capacitor Flash LED Driver

LM2758 is an integrated low-noise, high-current switched capacitor DC/DC converter with a regulated current sink.

The device is capable of driving loads up to 700 mA from a singlecell Li-Ion battery.

Maximum efficiency is achieved over the input voltage range by actively selecting the proper gain ba
