SY8008C中文资料High Efficiency 1.5MHz, 0.6A/1A/1.2ASynchronous Step Down Regulator数据手册Silergy规格书

描述 Description

The SY8008A/B/C are high-efficiency 1.5MHz synchronous step-down DC-DC regulator ICs capable of delivering up to 1A output currents. The SY8008 family 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.

Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1.5MHz switching frequency. This along with small SOT-23/TSOT-23 footprint provides small PCB area application
