Single Phase Core Controller for VR12.6

OVERVIEW

The ISL95813 single-phase controller provides a fully compliant 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 compared 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.

The ISL95813 has several other key features that include: DCR current sensing with single NTC thermal compensation; discrete resistor current sensing; differential remote voltage feedback; and user-programmable boot voltage, IMAX , TMAX , voltage transition slew rate and switching frequency.

KEY FEATURES
