DATASHEET ISL62773 Multiphase PWM Regulator for AMD Fusion™ Desktop CPUs Using SVI 2.0 FN8263 Rev 1.00 Dec 16, 2015 The ISL62773 is fully compliant with AMD Fusion™ SVI 2.0 and provides a complete solution for desktop microprocessor and graphics processor core power. The ISL62773 controller supports two Voltage Regulators (VRs) with three integrated gate drivers and two optional external drivers for maximum flexibility. The Core VR can be configured for 3-, 2-, or 1-phase operation while the Northbridge VR supports 2- or 1-phase configurations. The two VRs share a serial control bus to communicate with the AMD CPU and achieve lower cost and smaller board area compared with two-chip solutions. The PWM modulator is based on Intersil’s Robust Ripple Regulator R3™ technology.
