NCP81255

Single‐Phase Voltage

Regulator with Intel

Proprietary Interface for

Computing Applications

The NCP81255 is a high-performance, low-bias current,

single-phase regulator with integrated power MOSFETs intended to

support a wide range of computing applications. The device is able to

deliver up to 14 A TDC output current on an adjustable output with

Intel proprietary interface interface. Operating in high switching

frequency up to 1.2 MHz allows employing small size inductor and

capacitors. The controller makes use of ON Semiconductor’s patented

high performance RPM operation. RPM control maximizes transient

response while allowing for smooth transitions between

discontinuous-frequency-scaling operation and continuous-mode

full-power operation. The NCP81255 has an ultra-low offset current

monitor amplifier with programmable offset compensation for

high-accuracy current monitoring.
