FAN53528 Datasheet Digitally Programmable Buck Regulator

Manufacturer: onsemi

Overview: FAN53528 3.0 A, 2.4 MHz, Digitally Programmable Buck Regulator.

General Description

s The FAN53528 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 FAN53528 is capable of delivering 3.0 A continuous at over 80% efficiency, maintaining that efficiency at load currents as low as 10 mA.
