NCP81248 General Description

The NCP81248 contains a two−phase, and two single−phase buckregulator controllers optimized for Intel IMVP8 compatible CPUs.The two−phase controller combines true differential voltagesensing, differential inductor DCR current sensing, input voltagefeed−forward, and adaptive voltage positioning to provide accuratelyregulated power for IMVP8 CPU.The two single−phase controllers make use of ON Semiconductor’spatented high performance RPM operation. RPM control maximizestransient response while allowing smooth transitions betweendiscontinuous frequency scaling operation and continuous mode fullpower operation. The single−phase rails have a low offset currentmonitor amplifier with programmable offset compensation for highaccuracy current monitoring.
