The RT8125C/D PWM controller provides high efficiency,
excellent transient response, and high DC output accuracy
needed for CPU core, I/O, and chipset RAM supplies in
notebook computers.
Richtek Mach ResponseTM technology is specifically
designed for providing 100ns “instant-on” response to
load transients while maintaining a relatively constant
switching frequency.
The RT8125C/D achieves high efficiency at a reduced cost
by eliminating the current sense resistor found in
traditional current mode PWMs. Efficiency is further
enhanced by its ability to drive very large synchronous
rectifier MOSFETs. The Buck conversion allows this device
to directly step down high voltage batteries at the highest
possible efficiency. The RT8125C/D provides an 1% high
accuracy 0.8V reference voltage with minimum 1mA
source/sink current for high accuracy output application.
