NCP81248MNTXG Description
The NCP81248MNTXG contains two?phase, and two single?phase buck regulator controllers optimized for Intel IMVP8 compatible CPUs. The two?phase controller combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed?forward, and adaptive voltage positioning to provide accurately regulated power for IMVP8 CPU. The two single?phase controllers make use of ON Semiconductor’s patented high-performance RPM operation. RPM control maximizes transient response while allowing smooth transitions between discontinuous frequency scaling operation and continuous mode full power operation.
