General Description

The SY8113B1 is a high efficiency, 1.4MHz synchronous step-down DC/DC regulator capable of delivering up to 3A load current.

It can operate over a wide input voltage range from 4.5V to 18V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

The SY8113B1 adopts the instant PWM architecture to achieve fast transient responses for high step down applications.

Overview
