NCP81174
NCP81174 is 4/3/2-Phase Synchronous Buck Controller manufactured by onsemi.
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 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.
Features
- Output Voltage up to 2.0 V with PWM VID Interface
- Support 1.8 V and 3.3 V VID...
