ISL62776 Multiphase PWM Regulator

Datasheet ISL62776 Multiphase PWM Regulator for AMD CPUs Using SVI2 The ISL62776 is fully compliant with AMD Serial VID Interface 2.0 (SVI2) and provides a complete solution for microprocessor and graphics processor core power. The ISL62776 controller supports two Voltage Regulators (VRs) that use external drivers for maximum flexibility. The Core VR can be configured for 4-, 3-, 2-, or 1-phase operation and the SOC VR supports 1-phase operation. The two VRs share a serial control bus to commu.
