Overview

Description

IR3578MTRPBF is a multi-phase PWM controller originally from International Rectifier (now Infineon). It’s designed to regulate high‑current processor/GPU power rails by coordinating external MOSFETs in multiple phases (VRM applications).
Key points:
- Purpose: VRM controller for CPU/GPU core voltages and other high‑current rails.
- Operation: Current‑mode control with programmable switching frequency and phase interleaving.
- Features: Soft-start, overcurrent/overvoltage protection, undervoltage lockout, fault reporting.
- Packaging: Pb‑free (MTRPBF) variant, suitable for tape‑and‑reel production.
- Use case: Requires external MOSFETs, sense components, and support circuitry to form a complete VRM. Common in motherboards, GPUs, servers, and high‑performance FPGAs/ASIC power rails.
Note: For exact electrical specs, pinout, voltage ranges, and programming, refer to the official datasheet.

Features

Here are the key features of IR3578MTRPBF (typical for this multiphase VRM controller):
- 3-phase interleaved multiphase buck controller for CPU/GPU VRMs
- External N-channel MOSFET gate-drive for high-side/low-side switches (synchronous rectification)
- Voltage-mode regulation with remote sensing and feedback (FB)
- Programmable switching frequency and phase interleave
- Soft-start and ramp tracking options
- Enable input and Power-Good/status outputs
- Cycle-by-cycle overcurrent protection with phase current balancing
- Overvoltage, undervoltage lockout, and thermal shutdown protections
- Fault reporting/diagnostics and latchable flags
- Flexible compensation/networking for stable Vout across loads
- Pb-free, MTRPBF package
Note: Always refer to the exact datasheet for precise pinout and electrical specs.

Package

It uses a Pb-free QFN package (Quad Flat No-Lead). The MTRPBF suffix indicates the Tape & Reel Pb-Free variant.

Pinout

Pin count: 28 pins (28-pin package).
Function: IR3578MTRPBF is a multiphase buck regulator controller/driver. It controls two phases of external MOSFETs for a voltage-regulator module (VRM), handling voltage feedback, current sense, enable/soft-start, and protection features (overcurrent/overvoltage) to regulate system voltages (e.g., CPU core).

Manufacturer

The IR3578MTRPBF is made by Infineon Technologies AG (the IR prefix comes from the former International Rectifier, now part of Infineon).
Infineon is a German multinational semiconductor company, a global leader in power semiconductors and related microelectronics.

Application

IR3578MTRPBF is a 3‑phase motor driver IC with integrated FETs for BLDC/PMSM motors. Typical applications include:
- Automotive actuators and EC fans
- Industrial drives (pumps, fans, conveyors, machine tools)
- Consumer appliances (washing/dishwashers, HVAC blowers)
- Robotics and automation (mobile robots, servo actuators)
- Any compact, efficient motor control in BLDC/PMSM systems
