NCP81149
Single-Phase Voltage
Regulator with SVID
Interface for Computing
Applications
High Switching Frequency, High
Efficiency, Integrated Power MOSFETs
The NCP81149, 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 NCP81149 is in a QFN48 6 x 6 mm package.
