3+1 Voltage Regulator for IMVP-7/VR12™ CPUs ISL95831 Compliant with IMVP-7/VR12™, the ISL95831 provides a complete solution for microprocessor and graphic processor core power supply.

It provides two Voltage Regulators (VRs) with three integrated gate drivers.

The first VR can be configured as 3-, 2- or 1-phase VR while the second output is 1phase VR, providing maximum flexibility.

The two VRs share the serial control bus to communicate with the CPU and achieve lower cost and smaller board area

ISL95831 Features

* Both outputs support DCR current sensing with single NTC thermistor for DCR temperature compensation or accurate resistor current sensing. Both outputs come with remote voltage sense, programmable VBOOT voltage, programmable IMAX, TMAX, adjustable switching frequency, OC protection and separate Pow
