LNK3207P - LinkSwitch-TN2 AC-DC Offline Switcher IC

The LNK3207P from Power Integrations is a highly integrated AC-DC offline switcher IC from the LinkSwitch-TN2 family, designed for non-isolated buck, buck-boost, and flyback topologies. This versatile power management solution features an internal switch with 725V breakdown voltage, 66kHz switching frequency, and comprehensive fault protection including current limiting, over-temperature, over-voltage, and short circuit protection.

Key Features:

  • Integrated internal switch with 725V breakdown voltage
  • 66kHz switching frequency with 69% duty cycle
  • Multi-topology support: Buck, Buck-Boost, Flyback
  • Advanced fault protection: Current limiting, OTP, OVP, short circuit
  • Control features: Enable, frequency control, soft start
  • Wide operating temperature range: -40°C to 150°C (TJ)
  • Through-hole 8-DIP package for easy integration
  • RoHS compliant for environmental compliance

Applications: Ideal for power supplies in industrial, consumer, and telecom applications requiring reliable, efficient AC-DC conversion with robust protection features.
