DATA SHORT To request the full datasheet, please visit www.intersil.com/products/isl95812 ISL95812 FN8380 Rev 0.00 Multiphase PWM Regulator for VR12.5, VR12.6 and VR12.6+ CPUs March 5, 2013 Fully compliant with Intel VR12.5, VR12.6 and VR12.6+ Features specifications, the ISL95812 provides a complete solution for Serial data bus microprocessor core power supply. It provides a Voltage Regulator (VR) with two integrated and one external gate Output configurable 3-, 2- or 1-phase using two integrated drivers. The VR can be configured as 3-, 2- or 1-phase, gate drivers providing maximum flexibility. The VR uses the serial control bus Precision core voltage regulation (SVID) to communicate with the CPU and achieves lower cost and - 0.5% system accuracy over-temperature smaller board area. - Enhanced load line accuracy 3 Based on Intersils Robust Ripple Regulator (R ) technology, Supports multiple current sensing methods the PWM modulator compared to traditional modulators, has - Lossless inductor DCR current sensing faster transient settling time, variable switching frequency - Precision resistor current sensing during load transients and has improved light load efficiency with its ability to automatically change switching frequency. Differential remote voltage sensing The ISL95812 has several other key features. The output Programmable V voltage at start-up BOOT supports DCR current sensing with single NTC thermistor for Resistor programmable I and voltage transition CCMAX DCR temperature compensation or accurate resistor current slew rate sensing. The output comes with remote voltage sense, programmable V voltage, programmable I , Adaptive body diode conduction time reduction BOOT CCMAX programmable voltage transition slew rate, adjustable switching frequency, overcurrent protection and Power-Good Applications output.
