TNY280PNAU - TinySwitch-III Offline Switching Power Supply IC

The TNY280PNAU from Power Integrations is a high-performance offline switcher IC from the TinySwitch-III family, designed for isolated flyback topology power supplies up to 36.5W. This integrated solution combines a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry on a single chip.

Key Features & Benefits:

  • Integrated Design: Reduces component count and simplifies PCB layout with built-in 700V MOSFET
  • Comprehensive Protection: Current limiting, over-voltage, over-temperature, short circuit, and open-loop fault protection
  • High Efficiency: 132kHz switching frequency with 65% duty cycle for optimal performance
  • Wide Operating Range: -40°C to 150°C junction temperature for demanding applications
  • Easy Integration: Standard through-hole 8-DIP package for reliable assembly

Typical Applications:

  • AC-DC power supplies for industrial equipment
  • Automotive auxiliary power systems
  • Aerospace avionics power modules
  • Telecommunications infrastructure
  • Battery chargers and adapters

Quality & Authenticity Guarantee:

All TNY280PNAU units are sourced directly from authorized Power Integrations distributors with full manufacturer documentation, traceability, and long lifecycle support. Each IC is factory-tested and comes with complete datasheets and application notes.
