RT5771A规格书详情

General Description

The RT5771A 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 wide range of loads and output capacitors.

The RT5771A is available in a WDFN-10L 3x3 package.
