Typical Application


SY20108 is a high efficiency 3MHz synchronous step down DC/DC regulator IC capable of delivering up to1Aoutput current. It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.
