FAN53601 Datasheet Synchronous Buck Regulator

Manufacturer: onsemi

Overview: Synchronous Buck Regulator, 1 A 6 MHz, 600 mA FAN53601, FAN53611.

General Description

The FAN53601/11 is a 6 MHz, step−down switching voltage regulator, available in 600 mA or 1 A options, 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 FAN53601/11 is capable of delivering a peak efficiency of 92%, while maintaining efficiency over 80% at load currents as low as 1 mA.

The regulator operates at a nominal fixed frequency of 6 MHz, which reduces the value of the external ponents to as low as 470 nH for the output inductor and 4.7 mF for the output capacitor.
