SY8023FCC中文资料双通道降压型开关式直流稳压控制IC(内置MOSFET ,2.5-5.5Vin, Dual 3A Sync Buck数据手册Silergy规格书

描述 Description

The SY8023 is a high-efficiency 1MHz synchronous step-down DC-DC regulator IC capable of delivering up to 3A output currents. The SY8023 operates over a wide input voltage range from 3V 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 1MHz switching frequency.
