The ISL6265A is a multi-output controller with integrated MOSFET drivers for AMD SVI capable mobile CPUs. It features a single-phase controller for the Northbridge portion of the CPU and two additional channels that can be configured for two-phase or individual single-phase outputs. The ISL6265A can be used for both uniplane and dual-plane processors. It utilizes Intersil's R3 Technology™ for faster transient response.
The ISL6265A is a multi‑output controller with embedded MOSFET gate drivers designed for AMD mobile CPUs. It can operate as a single‑phase controller for the Northbridge (VDDNB) and as dual‑phase or independent single‑phase controllers for other CPU planes.
The device features Intersil’s patented R3 Technology™ ripple regulator, a serial VID interface (SVI) for fine voltage adjustment, differential remote‑CPU die sensing, and built‑in over‑voltage, under‑voltage and over‑current protection.
