The ISL6324 is a monolithic dual PWM hybrid controller with I2C interface designed by Linear Technology for AMD SVI Split-Plane and PVI Uniplane processors. This device supports dual outputs, including a multiphase controller supporting uniplane VDD core voltage and a single phase controller supporting Northbridge (VDDNB) voltage. In SVI mode, ISL6324's multiphase controller is active, only supporting uniplane VDD processors. In PVI mode, ISL6324's multiphase controller is not active, only supporting uniplane VDD processors.
The ISL6324 is a monolithic dual PWM hybrid controller that powers AMD SVI and PVI split‑plane processors. It integrates two synchronous buck converters, internal MOSFET drivers and an I²C interface for programmable voltage offsets, over‑voltage and over‑current protection.
