NCP81174 Overview
NCP81174 4/3/2-Phase Synchronous Buck Controller with Power Saving Mode and PWM VID Interface The NCP81174 is a general−purpose up to four−phase synchronous buck controller. It bines differential voltage sensing, differential phase current sensing, and PWM VID interface to provide accurate regulated power for the puter or graphic controllers. It can receive power saving mand (PSI) from processors and operates in...
