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.

• Serial data bus, dual outputs
• Configurable 3-, 2- or 1-phase for the 1st output using one integrated gate driver
• Configurable 2- or 1-phase for the 2nd output using one integrated gate driver
• Excellent transient response, high light load efficiency
• 0.5% system accuracy over-temperature, lossless inductor DCR current sensing
• Precision resistor current sensing, differential remote voltage sensing
• Programmable VBOOT Voltage at Start-up
• Resistor programmable IMAX, switching frequency for both outputs
• Adaptive body diode conduction time reduction
• 40-TQFN package, operating temperature range from -10°C to 100°C
