SY8401ABC.PDF
SY8401 55V高耐压异步降压变换器
概述：
The SY8401 develops a high efficiency asynchronous step down DC/DC regulator capable of delivering 0.8A output current. The IC adopts current mode adaptive constant off time control. The SY8401 operates over a wide input voltage range from 4.5v to 55v and integrates main switch with very low Rds(on) to minimize the conduction loss
Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1.2MHz switching frequency
