SY8303 - Synchronous Step Down Regulator

Datasheet Summary

Description

The SY8303 develops a high efficiency synchronous step-down DC-DC converter capable of delivering 3A load current.

The SY8303 operates over a wide input voltage range from 4.5V to 40V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.

Features

ultra low quiescent operating to achieve high efficiency under light load. And the internal soft-start limits inrush current during power on. SY8303 is available in TSOT23-8 package. Ordering Information SY8303.

Applications Note: SY8303 High Efficiency Fast Response, 3A, 40V Input Synchronous Step Down Regulator General Description The SY8303 develops a high efficiency synchronous step-down DC-DC converter capable of delivering 3A load current. The SY8303 operates over a wide input voltage range from 4.5V to 40V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. The SY8303 adopts peak current control scheme. The switching frequency is adjustable from 500kHz to 2.5MHz 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. SY8303 is available in TSOT23-8 package.
