Typical Application

Description

The SY20041 is a high-efficiency 1.5MHz synchronous step-down DC-DC converters capable of delivering up to1.5Aoutput current. It operates over a wide input voltage range from 2.5V to 5.5V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. 

Applications

·       Wireless LAN Card

·       DVD Blu-ray Drive

·       USB Datacard
