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
ISL62776 Features
* Supports AMD SVI 2.0 serial data bus interface ○ Serial VID clock frequency range: 100kHz to 25MHz
* Dual output controller with PWM output
* Precision voltage regulation ○ 0.5% system accuracy over-temperature ○ 0.5V to 1.55V in 6.25mV steps ○ Enhanced load-line accuracy
