The ISL95853A, fully compliant with Intel IMVP8™ specifications, provides a complete solution for microprocessor core power supply. It also provides a Voltage Regulator (VR) with two integrated and one external gate drivers. The VR can be configured as 3-, 2- or 1-phase, providing maximum flexibility. The VR uses the serial control bus (SVID) to communicate with the CPU and achieves lower cost and smaller board area. Based on Intersil’s Robust Ripple Regulator (R3™) technology, the PWM modulator compared to traditional modulators, has faster transient settling time, variable switching frequency during load transients and has improved light-load efficiency with its ability to automatically change switching frequency. The ISL95853A has several other key features. The output supports DCR current sensing with single NTC thermistor for DCR temperature compensation or accurate resistor current sensing. The output comes with remote voltage sense, programmable VBOOT voltage, programmable ICCMAX, programmable voltage transition slew rate, adjustable switching frequency, overcurrent protection and power-good output.
