onsemi FAN53526UC224X, Step Down DC-DC Converter, 6.25mA, WLCSP

The ON Semiconductor series FAN53526 is a step−down switching voltage regulator that delivers a digitally programmable output from an input voltage supply of 2.5 V to 5.5 V. The output voltage is programmed through an I2C interface capable of operating up to 3.4 MHz Using a proprietary architecture with synchronous rectification, the FAN53526 is capable of delivering 3.0 A continuous at over 80% efficiency, maintaining that efficiency at load currents as low as 10 mA.
