Description

IR3567BMTRPBF is a multi‑phase buck regulator controller from International Rectifier (now Infineon) used to build CPU/GPU voltage‑regulator modules (VRMs). It provides PWM control and gate drive for external high‑ and low‑side MOSFETs across multiple phases, delivering fast transient response and tight core‑voltage regulation. Typical features include current‑mode control, programmable switching frequency, and protection mechanisms (overcurrent/overvoltage, fault reporting) with adjustable output voltage via external resistor networks. The MTRPBF suffix denotes the Pb‑free, RoHS‑compliant package variant used in compact VRM designs. The device is intended for high‑efficiency, high‑current voltage regulation in computing systems and similar applications. For exact specifications, pinout, recommended external components, and packaging details, consult the official IR3567B/IR3567M datasheet and packaging notes from Infineon.

Features

IR3567BMTRPBF is a multi‑phase buck controller for VRMs. Key features:
- 4‑phase interleaved PWM controller for CPU/GPU power rails.
- External FET drive: drives high‑side/low‑side MOSFETs; requires external power stages.
- Programmable switching frequency in the VRM range (typical 200–600 kHz range, configurable).
- Voltage‑mode control with external compensation for precise regulation.
- Adjustable output voltage via resistor network; supports tracking and soft‑start.
- Comprehensive protection: overvoltage, undervoltage, cycle‑by‑cycle overcurrent, and overtemperature with latch/reset.
- Fault reporting and power‑good / soft‑start sequencing; enables controlled ramp and startup.
- Optional current‑sense input for enhanced current limit accuracy.
- Pb‑free, tape‑and‑reel package (MTRPBF) for reliable board assembly.
Note: Requires external MOSFETs and surrounding power components per reference design.

Pinout

- Pin count: 40 pins (QFN package, MTRPBF variant)
- Function: Multi‑phase PWM controller for voltage regulator modules (VRMs); drives external MOSFETs across multiple phases and provides feedback, timing, soft‑start, and protection (OC/OV/UVLO, etc.) for CPU core voltage regulation.

Manufacturer

- Manufacturer: Infineon Technologies AG (brand originally International Rectifier).
- What kind of company: A German global semiconductor company that designs and manufactures power management ICs, MOSFETs, drivers, and other energy‑efficient electronic components for automotive, industrial, and consumer markets.

Application

IR3567BMTRPBF is a multi-phase buck controller used for high-current VRMs. Typical application areas include:
