DATA SHORT To request the full datasheet, please visit www.intersil.com/products/isl95813 ISL95813 FN8449 Rev 2.00 Single-Phase Core Controller for VR12.6 January 29, 2015 The ISL95813 single-phase controller provides a fully Features compliant VR12.6 power supply solution for Intel Full VR12.6 specification compliance microprocessors. It provides a tightly regulated output voltage that is programmed through a high speed serial bus interface Wide input voltage range: 4.6V to 25V with the CPU. This interface also allows the CPU to acquire R3 control architecture delivers excellent transient real-time information from the voltage regulator (VR), which response and power state mode transitions includes load current and VR temperature. Current monitor (IMON) with temperature compensation Based on Intersil s Robust Ripple Regulator R3 Technology, VRHOT indicator for CPU protection the PWM modulator provides faster transient response and settling time when compared against traditional modulation Digitally selectable switching frequency: schemes. Its variable frequency topology also allows for - 425kHz, 550kHz, 700kHz with ECO and PRO options natural period stretching Discontinuous Conduction Mode Enhanced light-load efficiency discontinuous conduction (DCM) for increased efficiency and power savings in light load mode operation situations. Ultra small 20 Ld 3mmx4mm QFN package The ISL95813 has several other key features that include: DCR current sensing with single NTC thermal compensation Enable and power-good monitor discrete resistor current sensing differential remote voltage feedback and user-programmable boot voltage, I , T , Applications MAX MAX voltage transition slew rate and switching frequency.
