SY8003 Overview
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...
