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.
