Overview

Description

ISL6567CRZ-T is a high-performance PWM controller from Intersil/Renesas used for VRMs (voltage regulator modules). It drives external MOSFETs in a multi‑phase buck converter to generate CPU/GPU core voltages.
Key points:
- Multi‑phase buck controller for high-current regulators
- Programmable switching frequency and phase management
- Voltage regulation via feedback with soft-start
- Protection features: over‑current, over‑voltage, under‑voltage, and thermal/OTP protections
- Enable/shutdown control and fault handling
Typical use: CPU/GPU core voltage regulators and other high‑current VRMs requiring tight regulation and phase-balanced operation.
Package note: CRZ is the specific package code; -T typically means tape-and-reel shipment. Requires external MOSFETs, inductor, and sense/feedback components.

Features

ISL6567CRZ-T is a dual-channel, interleaved, synchronous buck controller designed for CPU/core voltage rails. Key features:
- Two-channel PWM controller for synchronous buck regulators (external N‑MOSFETs)
- Current-mode control with slope compensation
- Interleaved/multiphase operation for reduced input ripple and improved transient response
- Programmable switching frequency (broad range)
- Output voltage adjustable via feedback network; supports remote sense
- Enable input and soft-start control
- Protections: UVLO, overcurrent/short-circuit with protection (hiccup), overvoltage
- Thermal shutdown
- Power-Good/status output and fault reporting
- Suitable for high-current multiphase designs (CPU/GPU rails)
- Packaging: CRZ package
Note: For exact pinout, electrical specs, and recommended operating conditions, refer to the official datasheet.

Package

ISL6567CRZ-T is in a CRZ leadless QFN package (Intersil/QFN family). The “-T” suffix denotes tape-and-reel version.

Pinout

Pin count: 28 pins (CRZ is a 28‑pin package; “-T” denotes tape-and-reel).
Function: Dual-channel, synchronous buck PWM controller. Provides two independent gate-drive outputs (PHASEA/PHASEB) for a two‑phase buck converter, with inputs for feedback (FB1/FB2), current sense (ISENSE1/ISENSE2), enable, soft-start, reference, VCC, and protections plus PGOOD—suitable for multi-rail VRMs.

Manufacturer

- Manufacturer: Intersil (now a part of Renesas Electronics Corporation).
- What kind of company: A semiconductor company that designs and manufactures analog and power-management integrated circuits.

Application

ISL6567CRZ-T is a dual-channel, multiphase buck controller for VRMs. Typical applications: CPU/GPU core voltage regulation in desktops/servers, multi‑phase VRMs for compute platforms, FPGA/ASIC core and memory rails, and telecom/network DC-DC power modules requiring high efficiency and fast transient response.

Equivalent

There isn’t a single exact cross-reference for ISL6567CRZ-T. Equivalents depend on specs. Please share: input voltage range, total/phase current, required switching frequency, number of phases, package, and whether you need external or integrated MOSFETs. With these, I can suggest closest alternatives from TI, Analog Devices, Renesas, etc.
