The ISL6323 is a hybrid SVI/PVI monolithic dual PWM hybrid controller that powers AMD SVI split-plane and PVI uniplane processors
The ISL6323 dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. It supports hybrid power control of AMD processors via either a 6‑bit parallel VID interface (PVI) or a serial VID interface (SVI). The device integrates two power MOSFET drivers, reducing external component count and offering features such as output voltage droop, fully differential current sensing, and dual‑edge modulation.
The datasheet includes ordering information, pinout diagrams, typical application circuits for both SVI and PVI modes, absolute maximum ratings, detailed electrical specifications, layout guidelines for UGATE/LGATE/PHASE traces, thermal management recommendations, and a package outline drawing.
