W49C65-12H

Precision Multi-Phase Synchronous Buck Switching Regulator Controller IC, combining high-accuracy internal reference windows, dynamic pulse-width modulation (PWM) feedback logic, and high-drive gate outputs on a single substrate. It functions as a localized, high-efficiency voltage regulation controller designed specifically to deliver clean step-down DC power rails to microprocessors and memory buses within computing platforms, housed in a surface-mount configuration. Manufactured by IC Works / Cypress Semiconductor.
