Description

Compliant with IMVP-7/VR12, the ISL95836 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 VR could be configured as 2- or 1-phase VR, providing maximum flexibility.

The ISL95836 has several other key 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, IMAX and switching frequency, adjustable OC protection and separate Power-Good.

Features

• Serial Data Bus

• Dual Outputs :
(1) Configurable 3-, 2- or 1-phase for the 1st Output using 2 integrated Gate Drivers
(2) Configurable 2- or 1-phase for the 2nd Output using an Integrated Gate Driver

• Differential Remote Voltage Sensing

• Programmable VBOOT Voltage at Start-up
