RT8075 Dual 1A, 1.25MHz Synchronous Step-Down Converter General Description 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.
