RT8125H - Richtek

RT8125H High Efficiency Single Synchronous Buck PWM Controller

The RT8125H 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 freq.
