SY8303 內置MOS 40V/3A同步降壓轉換器
概述：
The SY8303 develops a high efficiency synch 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 Rps(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 eatures 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
