概要

Description

ISL6625ACRZ-T is a dual-channel, fixed-frequency PWM controller used to build multi-phase buck regulators (VRMs). It generates two independent, interleavable PWM signals to drive external MOSFETs, enabling low‑noise, high‑efficiency CPU/GPU core voltage rails. Key features include current‑mode control with slope compensation, soft‑start, enable/disable control, and protection functions (overcurrent, undervoltage, overvoltage/thermal). Switching frequency is programmable (and can be synchronized to an external clock) via external components, making it suitable for two‑phase or multiphase interleaved designs. The device is designed for a typical control supply around 4.5–5.5 V and is offered in a RoHS-compliant package with tape-and-reel option (suffix -T). Applications include CPU/GPU memory and core power regulators in computers, servers, and telecom equipment. In short, ISL6625ACRZ-T is a compact, protection-rich controller for robust, multi‑phase buck regulation.
