概述
Description
ISL6567CRZ-T is an Intersil/Renesas PWM controller for DC-DC buck converters, intended for multi‑phase VRMs used in CPUs, GPUs, and other high‑power systems. It is an analog controller that drives external MOSFETs to regulate a high input voltage down to a low, stable core rail. The CRZ-T suffix indicates the package type (CRZ) with tape‑and‑reel packaging.
Key features (typical):
- Programmable switching frequency with multi‑phase support
- Error amplifier/feedback path for voltage regulation
- Enable, soft‑start and sequencing controls
- Protection: overcurrent, overvoltage, undervoltage; fault reporting
- Remote sensing and potential coherence/sharing between phases
Applications:
- CPU/GPU core voltage regulators
- Server, telecom, and other high‑efficiency VRMs
Note: ISL6567CRZ-T is a controller; it requires external MOSFETs, inductors, and other passive components. For exact specs, pinout, and recommended circuitry, consult the latest datasheet.
