FAN53741 Datasheet Synchronous Buck Regulator

Manufacturer: onsemi

General Description

The FAN53741 is a 2.5 MHz step−down switching voltage regulator, that delivers a fixed output from an input voltage supply of 2.3 V to 5.5 V.

Using a proprietary architecture with synchronous rectification, the FAN53741 is capable of delivering a peak efficiency of 97% and can support a max load of 1300 mA.

The regulator operates at a nominal fixed frequency of 2.5 MHz, which reduces the value of the external components achieving a total solution size of 5.24 mm2.
