High Efficiency 1.5MHz, Dual 1.5A/1A Synchronous Step Down Regulator

The SY8021L and SY8021 are high-efficiency 1.5MHz synchronous step-down DC-DC regulators ICs capable of delivering up to 1A and 1.5A output currents,respectively. The SY8021 operates over a wide input voltage range from 3V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON • Low RDS(ON) for internal switches (top/bottom):\r\n• 3-5.5V input voltage range\r\n• Internal softstart limits the inrush current\r\n• RoHS Compliant and Halogen Free\r\n• Compact and thermally enhanced package: SO8E;
