This is a Monolithic Dual PWM Hybrid Controller that supports AMD SVI Split-Plane and PVI Uniplane processors and provides high efficiency and tight regulation of synchronous buck DC/DC converters.
The ISL6323A dual PWM controller provides high‑efficiency, tight regulation for two synchronous buck converters, supporting both serial (SVI) and parallel (PVI) VID interfaces used by AMD processors. It integrates MOSFET drivers, offers load‑line programming, and can shed phases for light‑load efficiency.
Key features include multi‑phase core voltage regulation, differential remote voltage sensing, adaptive phase alignment, over‑current and over‑voltage protection, selectable switching frequency up to 1 MHz, and a 5 V‑12 V variable gate‑drive bias.
