LM2758 Datasheet (Texas Instruments) - Switched Capacitor Flash LED Driver

LM2758, Switched Capacitor Flash LED Driver

The LM2758 device is an integrated low-noise, highcurrent switched capacitor DC-DC converter with a regulated current sink.

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

Maximum efficiency is achieved over the input voltage range by actively selecting the pro
