RT5771B
3A, 1MHz, Synchronous Step-Down Converter
General Description
The RT5771B is a high efficiency synchronous, step-down DC-DC converter.
Its input voltage ranges from 2.
7V to 5.
5V that provides an adjustable regulated output voltage from 0.
6V to VIN while delivering up to 3A of output current.
The internal synchronous low on-resistance power switches increase efficiency and eliminate the need for an external
Schottky diode.
The switching frequency is fixed internally at 1MHz.
The 100% duty cycle provides low dropout operation, hence extending battery life in portable systems.
Current mode operation with internal compensation allows the transient response to be optimized over a wid...
