RT8035A Datasheet 1.25MHz Synchronous Step-Down Converter

Manufacturer: Richtek

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.
