개요

Description

IR3447MTRPBF is a high-voltage PWM controller IC from International Rectifier (now Infineon) used in off-line switch-mode power supplies and adapters. It drives an external power MOSFET in flyback or similar topologies, starting from rectified mains and regulating output via feedback.
Key features (typical):
- High-voltage startup and operation
- Current-mode control with a sense input
- Soft-start and fixed or programmable switching frequency
- Overcurrent/short-circuit protection
- Overvoltage protection, undervoltage lockout
- Thermal shutdown
Package note:
- MTRPBF denotes Tape & Reel, Pb-free packaging.
Typical uses:
- AC-DC wall adapters, small power supplies, LED drivers, and other SMPS applications.

Package

I don’t have live datasheet access, so I can’t reliably state the IR3447MTRPBF package from memory. Please provide the datasheet or allow me to look it up and I’ll return the exact package type.

Manufacturer

Manufacturer: International Rectifier (IR), a brand now owned by Infineon Technologies.
What kind of company: Infineon (formerly International Rectifier as the IR brand) is a global semiconductor company that designs and manufactures power semiconductors, MOSFETs, power-management ICs and related solutions for automotive, industrial, consumer and communications markets.

Application

IR3447MTRPBF is a primary-side PWM controller for flyback offline switched‑mode power supplies. Typical applications include:
- Offline AC‑DC adapters and battery chargers
- Constant‑current LED driver circuits
- Small to medium telecom and industrial switch‑mode PSUs
- Any flyback-based SMPS needing current‑mode control, startup, current limit, and protection features.
