Overview: Single Phase Core Controller for VR12.6 ISL95813
The ISL95813 single-phase controller provides a fully pliant VR12.6 power supply solution for Intel™ microprocessors. It provides a tightly regulated output voltage that is programmed through a high speed serial bus interface with the CPU. This interface also allows the CPU to acquire real-time information from the voltage regulator (VR), which includes load current and VR temperature.
Based on Intersil's Robust Ripple Regulator (R3™) technology, the PWM modulator provides faster transient response and settling time when pared against traditional modulation schemes. Its variable frequency topology also allows for natural period stretching discontinuous conduction mode (DCM) for increased efficiency and power savings in light load situations.
