SY8088I中文资料High Efficiency, 1.5MHz, 1A Synchronous Step Down Regulator数据手册Silergy规格书

描述 Description

SY8088I is a high efficiency 1.5MHz synchronous step down DC/DC regulator capable of delivering up to 1A output current. It can operate 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.

The low output voltage ripple, the small external inductor and the capacitor sizes are achieved with 1.5MHz switching frequency.
