NCP81174N

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. Dual−edge current mode 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 VID Interface Remote Differential Output Voltage Sense Differential Current Sense for Each Phase 200 kHz − 1000 kHz Switching Frequency PWMVID Frequency up to 5 MHz Power Saving Interface (PSI) Power Good Output Thermally Compensated Current Monitoring Over Current Protection Fast Transient Response Latched OVP and UVP Protections QFN−32, 5 x 5 mm, 0.5 mm Pitch Package This is a Pb−Free Device Typical Applications GPU and CPU Power Graphics Card Applications www.onsemi.com 1 32 QFN32 MN SUFFIX CASE 488AM MARKING DIAGRAM 1 81174N AWLYYWWG G A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week G = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION Device Package Shipping† NCP81174NMNTXG QFN32 2500 / Tape & (Pb−Free) Reel †For...
