ISL95836HRTZ-T

ISL95836HRTZ-T is a dual 3+2 PWM controller for IMVP-7/VR12™ CPUs. It provides a complete solution for IMVP-7/VR12™ compliant microprocessor and graphic processor core power supplies. It provides the control and protection for two Voltage Regulators (VRs). The first VR, typical for Vcore, incorporates 2 integrated drivers and can operate in 3-, 2- or 1-phase configurations. The second VR, typical for graphics, incorporates 1 integrated driver and can operate in 2- or 1-phase configurations. The two VRs share a serial control bus to communicate with the CPU and achieve lower cost and smaller board area compared with the two-chip approach. Both VRs utilize Intersil’s Robust Ripple Regulator R3 Technology™. The Applications include IMVP-7/VR12-compliant computers.
