描述 Description

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):

? I2C Controlled

? Logic Controlled (pin selectable VOUT)

Both options have automatic DCM/CCM mode operation

with Forced CCM control.
