Overview
® RT8035A Dual 800mA, 1.
25MHz Synchronous Step-Down Converter General Description The RT8035A is a high-efficiency Pulse-Width-Modulated (PWM) dual step-down DC/DC converter.
Capable of delivering up to 800mA output current over a wide input voltage range from 2.
5V to 6V, the RT8035A 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 RT8035A enters Low-Dropout mode when normal PWM cannot provide regulated output voltage by continuously turning on the upper P-MOSFET.
The RT8035A enters shut-down mode and consumes less than 0.
1μA when the EN pin is pulled low.
The switching ripple is eas...
