RT8020 Datasheet | Richtek

Dual High-Efficiency PWM Step-Down DC-DC Converter General Description The RT8020 is a dual high-efficiency Pulse-WidthModulated (PWM) step-down DC-DC converter. It is capable of delivering 1A output current over a wide input voltage range from 2.5V to 5.5V, the RT8020 is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources within .. the range such as cellular phones, PDAs and other handheld devices. Two operational modes are available : PWM/Low-Dropout auto-switch and shutdown modes. Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode. No external Schottky...
