Description
This is 3+1 Voltage Regulator.
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 1-phase 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 compared with the two-chip approach.
Features
1. Serial Data Bus
2. Dual Outputs :
(1) Configurable 3-, 2- or 1-phase for the 1st Output using 2 integrated Gate Drivers
(2) 1-phase for the 2nd Output using an Integrated Gate Driver
3. 0.5% System Accuracy Over-Temperature
4. Supports Multiple Current Sensing Methods
(1) Lossless Inductor DCR Current Sensing
(2) Precision Resistor Current Sensing
5. Differential Remote Voltage Sensing
6. Programmable VBOOT Voltage at Start-up
