The LNK302DN-TL from Power Integrations is a non-isolated offline switcher supporting Buck, Buck-Boost, and Flyback topologies with an integrated 700V power switch. It runs at 66kHz with 69% maximum duty cycle in a 7-lead 8-SOIC package. Current limiting, open loop, over temperature, and short circuit protection are integrated, with a -40°C to 150°C junction temperature range for LinkSwitch-TN applications.
- Supports Buck, Buck-Boost, and Flyback topologies in one non-isolated device.
- Integrated 700V switch simplifies design and lowers BOM cost.
- 66kHz switching with 69% max duty cycle enables compact solutions.
- Comprehensive protection: current limiting, open loop, over temperature, short circuit.
- 8-SOIC package supports space-efficient surface-mount layouts.
Non-Isolated Buck Converters
The LNK302DN-TL provides direct-coupled Buck conversion for low-power AC-DC rails, using an integrated 700V switch to minimize external components.
Buck-Boost Auxiliary Supplies
Buck-Boost topology supports flexible output configurations for auxiliary bias in appliances and controls at 66kHz switching.
Compact Flyback Bias Rails
Where isolation is not needed, the Flyback option offers a simple non-isolated conversion path for small supplies.
Consumer Appliance Electronics
Built-in current limiting, open loop, over temperature, and short circuit protection support dependable operation in cost-sensitive designs.
Industrial Control Boards
The 8-SOIC package and -40°C to 150°C junction temperature range suit surface-mount control electronics.
