DESCRIPTION
LM2759 is an integrated low-noise, high-current switched capacitor DC/DC converter with a regulated current source. The device requires only four small ceramic capacitors making the total solution area less than 22 mm2 and the height less than 1 mm. The LM2759 is capable of driving loads up to 1A from a single-cell...
