The RT8020GQW is a dual high-efficiency pulse width modulated (PWM) step-down DC/DC Converter capable of delivering 1A output current over a wide input voltage range from 2.5 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. 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 diode is required in practical application. The RT8020 enters low-dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper PMOS. The RT8020 enter shutdown mode and consumes <0.1µA when EN pin is pulled low. The switching ripple is easily smoothed-out by small package filtering elements due to a fixed operation frequency of 1.5MHz.
● 95% Efficiency
● No Schottky diode required
