Descrição

Three Rail Controller with SVID Interface for IMVP8 CPU Applications

The NCP81236P contains a twophase, and two singlephase buck regulators optimized for Intel IMVP8 compatible CPUs. The twophase controller combines true differential voltage sensing, differential inductor DCR current sensing, input voltage feedforward, and adaptive voltage positioning to provide accurately regulated power for IMVP8 VCCVCGI rails. Each of the two singlephase controllers can be used for VNN depending on the part configuration. Both make use of ON Semiconductors patented enhanced RPM operation. RPM control maximizes transient response allowing for smooth transitions between discontinuous frequency scaling operation and continuous mode full power operation. The singlephase rails have an ultralow offset current monitor amplifier with programmable offset compensation for ultra high accuracy current monitoring. The NCP81236P offers three internal MOSFET drivers with a single external PWM signal.
