SY8856 Description
The SY8856 is a high efficiency 3MHz synchronous step down DC/DC regulator capable of delivering up to 4A output current. It operates over a wide input voltage range from 2.7V to 5.5V. It integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
