Typical Application


SY20214 is a high efficiency ultra low quiescent current, 1.25MHz synchronous step-down DC/DC regulator capable of delivering up to 4A output current.

SY20214 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.
