概要
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.
