SA24403 - Synchronous Step Down Regulator

General Description

The SA24403 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 3.5A load current.

The SA24403 operates over a wide input voltage range from 4.2V to 40V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

SA24403 High Efficiency Fast Response, 3.5A, 40V Input Synchronous Step Down Regulator General Description The SA24403 develops a high efficiency synchronous step-down DC/DC converter capable of delivering 3.5A load current. The SA24403 operates over a wide input voltage range from 4.2V to 40V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SA24403 adopts peak current control scheme. The switching frequency is adjustable from 300kHz to 2.2MHz using an external resistor. The device also features ultra low quiescent operating to achieve high efficiency under light load. And the internal soft-start limits inrush current during power on.
