TNY378GN-TL Offline Switcher IC - TinySwitch-PK Series

The TNY378GN-TL from Power Integrations is a high-performance offline switcher IC in the TinySwitch-PK family, designed for isolated flyback topology AC-DC power conversion applications up to 28W. This integrated switcher combines a 700V power MOSFET with advanced control circuitry, delivering reliable performance across industrial, consumer, and telecommunications applications.

Key Features & Benefits

  • 28W Power Output: Ideal for low-to-medium power AC-DC converters in chargers, adapters, and auxiliary supplies
  • 700V Breakdown Voltage: Ensures robust operation with high voltage margins for universal input applications
  • Integrated Protection: Built-in current limiting, overload, over-temperature, and over-voltage protection for enhanced reliability and safety
  • Wide Switching Frequency Range: 132kHz to 264kHz for optimized transformer design and reduced EMI
  • Surface Mount Package: Compact SMD-8C (8-pin gull wing) footprint for space-constrained designs
  • Extended Temperature Range: -40°C to 150°C junction temperature for demanding environments

Applications

The TNY378GN-TL is well-suited for aerospace, automotive, industrial control systems, and telecommunications equipment requiring compact, efficient, and reliable AC-DC power conversion with full isolation and comprehensive fault protection.

Authorized Distributor: We supply genuine Power Integrations components with full manufacturer documentation, traceability, and warranty support. Long lifecycle availability guaranteed for your critical design-in programs.
