General Description
The RT8004 is a high efficiency synchronous, step-down
DC/DC converter. Its input voltage range is from 2.65V to
5.5V and provides an adjustable regulated output voltage
from 0.8V to 5V while delivering up to 3A of output current.
The internal power switch with 75m
Ω
on-resistance
increases efficiency and eliminates the need for an external
Schottky diode. Switching frequency is set by an external
resistor or can be synchronized to an external clock. 100%
duty cycle provides low dropout operation extending
battery life in portable systems. External compensation
allows the transient response to be optimized over a wide
range of loads and output capacitors.
The RT8004 operates in Forced Continuous Mode which
reduces noise and RF interference. 100% duty cycle in
Low Dropout Operation further maximize battery life.
