  • The NCP81174 is a general−purpose up to four−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. Dual−edge multiphase PWM modulation ensures a fast transient response with minimum possible capacitors.
