SY8003DFC中文资料降压 (Buck) 变换器 Vin max < 7V数据手册Silergy规格书

描述 Description

The SY8003 and SY8003A are high-efficiency, high frequency synchronous step-down DC-DC regulator IC capable of delivering up to 3A output current. The

SY8003 and SY8003A operate over a wide input voltage range from 2.7V 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 greater than 1MHz switching frequency.

SY8003 integrates short circuit and over-voltage latchoff protection. \r
