The RT8004A is a high efficiency synchronous, step-down
DC/DC converter. With an input voltage range is from 2.7V
to 5.5V, it can provide adjustable regulated output voltage
from 0.8V to 5V while delivering up to 4.5A of output
current.
The internal power switch with 75mΩ on-resistance
increases efficiency and eliminates the need for an external
Schottky diode. Switching frequency is either set by an
external resistor or synchronized to an external clock.
100% duty cycle provides low dropout operation, hence
extending battery life in portable systems. External
compensation allows the transient response to be
optimized over a wide range of loads and output capacitors.RT8004AGCP 资料下载
