Overview
RT8202L/M Single Synchronous Buck Controller 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.
Efficiency is further enhanced by its ability to drive very large synchronous rectifier MOSFETs.
The RT8202L is available in a WQFN-16L 4x4 package and the RT8202M is available in a WQFN-16L 3x3 package.
