SY8133 Description

The SY8133 is a high efficiency 400 KHz synchronous step-down DC-DC converters capable of delivering 3A output current. SY8133 operates over a wide input voltage range from 4V to 15V 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 400KHz switching frequency.
