LNK306DG

LNK306DG - LinkSwitch-TN Offline Switcher IC

The LNK306DG from Power Integrations is a highly integrated AC-DC converter IC from the LinkSwitch-TN family, designed for non-isolated buck, buck-boost, and flyback topologies. This compact switcher combines a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry in a single 8-SOIC package.

Key Features & Benefits

• Integrated 700V MOSFET - Reduces component count and board space
• Multi-topology support - Buck, Buck-Boost, and Flyback configurations
• Comprehensive protection - Current limiting, open loop, over-temperature, and short circuit fault protection
• 66kHz switching frequency - Optimized for efficiency and EMI performance
• Wide operating temperature - -40°C to 150°C junction temperature range
• Surface mount package - 8-SOIC for automated assembly

Typical Applications

Ideal for low-power AC-DC power supplies in consumer electronics, industrial controls, smart home devices, LED lighting drivers, and auxiliary power supplies. The LNK306DG's integrated protection features and minimal external component requirements make it perfect for cost-sensitive, space-constrained designs.
