FAN53730 Datasheet (ON Semiconductor)

FAN53730, 3A COT Buck Regulator

The FAN53730 is a constant on time (COT) buck converter that supports a minimum of 3 A load current.

The device’s COT topology provides the fastest transient recovery and optimal efficiency vs load due to its variable frequency operation.

Two device options are available (see Ordering Information):
