概述

Description

IR3567BMTRPBF is a multi-phase buck regulator controller from International Rectifier (now Infineon) used to power CPU/GPU core rails. It drives external MOSFETs and coordinates several phases to achieve high-efficiency VRMs. Key features typically include multi-phase regulation, programmable switching frequency, soft-start, enable control, remote sensing, and robust protections (overcurrent, over-voltage, undervoltage, thermal). It also balances current across phases for low ripple. The MTRPBF suffix indicates Pb-free, Tape-and-Reel packaging. Common applications are desktop/server CPU and GPU voltage regulators and other multi-phase DC-DC converters.

Features

IR3567BMTRPBF features (highlights):
- High-performance multi-phase buck controller for CPU/GPU VRMs
- External MOSFET gate-drive outputs for flexible multi-phase operation
- Programmable switching frequency and phase shedding for efficiency
- Phase-balancing and accurate current sharing
- Flexible regulation via feedback/VID interface with remote sense
- Soft-start, enable input, and PGOOD signaling
- Robust protection: overcurrent, overvoltage, undervoltage, and overtemperature
- Fault handling with clean recovery
- Pb-free, Tape & Reel packaging (MTRPBF)

Package

IR3567BMTRPBF is supplied Pb‑free on tape & reel (the MTRPBF suffix). The IC itself is packaged in a 28‑lead QFN with exposed pad—see the datasheet for exact mechanical dimensions.

Pinout

Pin count: 32 pins (MTR package, RoHS Pb‑free).
Function: IR3567B is a multi‑phase synchronous buck PWM controller (typically used as a 3‑phase VRM controller). It generates phased PWM gate‑drive outputs for external MOSFETs, handles phase‑management/load‑sharing, VID/input voltage programming, startup/shutdown sequencing, over‑current/over‑voltage protection and monitoring/telemetry for CPU/GPU power regulation.

Manufacturer

Manufacturer: International Rectifier (IR), now part of Infineon Technologies (acquired 2015).
What kind of company: a semiconductor manufacturer specializing in power-management products—power ICs, MOSFETs, drivers and related power-discrete and module solutions for automotive, industrial, computing and consumer electronics.

Application

Application areas:
- Desktop/server CPU core and memory VRMs
- GPU/graphics card VRMs
- High-end motherboard VRMs
- Data-center/server power modules
- Telecom/industrial power supplies needing high-current multi-phase regulation
