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 wide range of loads and output capacitors.
The RT5771B is available in a WDFN-10L 3x3 package.资料下载
