Overview

NCP81174N 4/3/2-Phase Synchronous Buck Controller with Power Saving Mode and PWM VID Interface The NCP81174N is a general−purpose multi−phase synchronous buck controller.

It combines differential voltage sensing, differential phase current sensing, and PWM VID interface to provide accurate regulated power for the computer or graphic controllers.

It can receive power saving command (PSI) from processors and operates in single−phase diode emulation mode to obtain high efficiency in light load.
