概要

Description

IR3541MTRPBF is an Infineon/International Rectifier multiphase buck regulator controller. It is used to drive external MOSFETs in a multi‑phase buck converter to generate high-current, low-voltage rails (e.g., CPU/GPU core voltages). The device coordinates timing across phases, provides a PWM control architecture, and includes features such as soft-start, enable/disable and tracking, plus protection (overcurrent, overvoltage/undervoltage, thermal). It requires external MOSFETs, inductors, and sense components to form a complete VRM solution. The MTRPBF suffix denotes Pb‑free, tape‑and‑reel packaging. Typical applications include VRMs for computer CPUs/GPUs, servers, and other digital power systems demanding stable, high‑current low‑voltage regulation.

Features

IR3541MTRPBF is a multi-phase, synchronous buck controller for VRMs (CPU/GPU). Key features include:
- External N‑channel MOSFET gate drive with multi‑phase capability
- Programmable switching frequency and voltage-positioning (remote sensing)
- Current-mode PWM with slope compensation
- Soft-start and output tracking
- Protection: overcurrent/short‑circuit, overvoltage, undervoltage/UVLO, overtemperature (OTP)
- Fault reporting and Power-Good signaling
- Enable input and sequencing options
- Pb-free MTRPBF package (compact QFN-like package)
Note: exact timing ranges and pinout are in the datasheet; these are the typical features for this device.

Package

Pb-free molded Tape‑and‑Reel package (MTRPBF); an 8‑pin molded package.

Pinout

Pin count: 8 pins (MSOP-8/SOP-8 package).
Function: IR3541MTRPBF is a PWM controller for DC-DC buck regulators (VRM). It generates the PWM drive for external MOSFETs based on feedback, and includes oscillator, soft-start/current limit, and enable features (external MOSFETs required).

Manufacturer

Manufacturer: Infineon Technologies (the International Rectifier brand). Infineon is a German multinational semiconductor company that designs and manufactures power semiconductors, integrated circuits, and energy-efficient solutions for automotive, industrial, and consumer markets.

Application

Used for high-efficiency switch-mode power supplies and voltage regulators, including CPU/GPU VRMs (multi‑phase buck regulators), desktop/server brick PSUs, telecom/datacom power rails, industrial power supplies, and battery charging circuits.

Equivalent

Equivalent parts depend on your specs. There isn’t a single drop-in substitute for IR3541MTRPBF. Please share target input range, max output current, number of phases, required rails, and package. With that, I can suggest closest substitutes from TI, Analog Devices, ST, or RichTek.
