Texas Instruments  LM2758TLEV

The LM2758 is an integrated low-noise, high-current switched capacitor DC/DC converter with a regulated current source. The device is capable of driving loads up to 700mA from a single-cell Li-Ion battery. Maximum efficiency is achieved over the input voltage range by actively selecting the proper gain based on the LED forward voltage and current requirements
