NCP81246
NCP81246 is Three-Rail Controller manufactured by onsemi.
Three-Rail Controller with Intel Proprietary Interface for IMVP8 CPU Applications
The NCP81246 contains a two-phase, and two single-phase buck regulators optimized for Intel IMVP8 patible CPUs.
The two-phase controller bines true differential voltage sensing, differential inductor DCR current sensing, input voltage feed-forward, and adaptive voltage positioning to provide accurately regulated power for IMVP8 Rail2.
The two single-phase controllers can be used for Rail1, Rail3 and Rail4 rails. Both make use of ON Semiconductor’s patented enhanced RPM operation. RPM control maximizes transient response while allowing for smooth transitions between discontinuous frequency...
