  • 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.
