NCP81251

NCP81251 Single-Phase Voltage Regulator with SVID Interface for Computing Applications High Switching Frequency, High Efficiency, Integrated Power MOSFETs The NCP81251, a single−phase synchronous buck regulator, integrates power MOSFETs to provide a high−efficiency and compact−footprint power management solution for new generation computing CPUs. The device is able to deliver up to 14 A TDC output current on an adjustable output with SVID interface. Operating in high switching frequency up to 1.2 MHz allows employing small size inductors and capacitors while maintaining high efficiency due to integrated solution with high performance power MOSFETs. Current−mode RPM control with feedforward from both input power supply and output voltage ensures stable operation over wide operation condition. The NCP81251 is in a QFN48 6 x 6 mm package. Features Meets Intel® Server Specifications 5 V to 20 V Input Voltage Range 1.0 V/1.1 V Fixed Boot Voltage Adjustable Output Voltage with SVID Interface Integrated Gate Driver and Power MOSFETs Up to 14 A TDC Output Current 500 kHz ~ 1.2 MHz Switching Frequency Current−Mode RPM Control Programmable SVID Address and ICCMax Adaptive Voltage Positioning (AVP) Programmable DVID Feed−Forward to Support Fast DVID Feedforward Operation for Input Supply Voltage and Output Voltage Output Over−Voltage and Under−Voltage Protections External Current Limitation Programming with Inductor Current Sense QFN48, 6 x 6 mm, 0.4 mm Pi...
