LNK354GN - LinkSwitch-HF Integrated Offline Switcher IC

The LNK354GN from Power Integrations is a highly integrated offline switcher IC designed for cost-effective, space-saving AC-DC power conversion applications up to 5 watts. Part of the proven LinkSwitch-HF family, this device combines a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry onto a single monolithic IC.

Key Features & Benefits

  • Integrated 700V MOSFET - Reduces component count and board space
  • 200kHz switching frequency - Enables compact transformer designs
  • Comprehensive protection - Built-in current limiting, open loop, over-temperature, and short circuit protection
  • Flyback topology - Ideal for isolated power supplies
  • Wide operating temperature range - -40°C to 150°C junction temperature
  • Surface mount SMD-8B package - Optimized for automated assembly

Typical Applications

  • Cell phone chargers and adapters
  • Standby supplies
  • Auxiliary power supplies
  • Consumer electronics
  • White goods appliances

Quality & Compliance: RoHS compliant. Authorized distributor with full traceability and manufacturer warranty support.
