RT8075,PDF数据表下载

RT8075 pdf资料下载The RT8075 is a high efficiency Pulse-Width-Modulated (PWM) dual step-down DC/DC converter. Capable of delivering up to 1A output current over a wide input voltage range from 2.5V to 5.5V, the RT8075 is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources such as cellular phones, PDAs, PC WLAN card and hand-held devices. Three operating modes are available including : PWM mode, Low Dropout Mode and shut-down mode. The Internal synchronous rectifier with low RDS(ON) dramatically reduces conduction loss at PWM mode. No external Schottky diode is required in practical application. The RT8075 enters Low Dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper P-MOSFET. The RT8075 enters shutdown mode and consumes less than 0.1μA when the EN pin is pulled low.Datasheet pdf资料数据表下载
