SY20111C Datasheet | Silergy

Description SY20111A/B/C/D/E/F are high efficiency 3MHz synchronous step down DC/DC regulator ICs capable of delivering up to 1A output 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.
