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 compared with the two-chip approach.
Based on Intersil’s Robust Ripple
Regulator (R3) technology™, the PWM modulator compared to traditional modulators, has faster transient settling time, variable s...
