The ISL6323B is a monolithic dual PWM hybrid controller supporting AMD SVI split-plane and PVI uniplane processors, providing high efficiency and tight regulation
The ISL6323B is a monolithic dual PWM controller that powers AMD SVI split‑plane and PVI processors. It integrates two synchronous buck converters, offering multi‑phase core voltage regulation and a single‑phase north‑bridge regulator. The device includes advanced features such as output voltage droop, fully differential current sensing, and dual‑edge modulation for fast transient response.
The document contains detailed sections on features, pinout, block diagrams, typical SVI and PVI applications, absolute maximum ratings, electrical specifications, recommended operating conditions, and package dimensions. It also lists ordering information and handling cautions for the Pb‑free plastic‑packaged versions.
