General Description

The RT8132A 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 RT8132A achieves high efficiency at a reduced cost by eliminating the current sense resistor found in traditional current mode PWMs.
