FAN53730

3.0A, 2.7MHz, Digitally Programmable COT Buck Regulator

Overview

The FAN53730 is a constant on time (COT) buck converter that supports a minimum of 3 A load current. The device’s constant on time topology provides the fastest transient recovery and optimal efficiency vs load due to its variable frequency operation. Two options are available: a fully programmable I2C version, and a logic controlled fixed output voltage version (refer to Ordering Information for voltage options). Both versions provide automatic DCM/CCM mode operation with Forced CCM control.
