RT8202M Datasheet Single Synchronous Buck Controller

Manufacturer: Richtek

Overview: RT8202L/M Single Synchronous Buck Controller General.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The RT8202L/M PWM controller provides the high efficiency, excellent transient response, and high DC output accuracy needed for stepping down high voltage batteries to generate low voltage CPU core, I/O, and chipset RAM supplies in notebook computers.

The constant-on-time PWM control scheme handles wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency.

The RT8202L/M achieves high efficiency at a reduced cost by eliminating the current-sense resistor found in traditional current mode PWMs.
