The Power Integrations LNK305DN-TL is a LinkSwitch®-TN offline AC-DC switcher with an integrated 700V power switch, supporting Buck, Buck-Boost, and Flyback topologies in non-isolated configurations. It switches at 66kHz with up to 69% duty cycle and includes current limiting, open loop, over temperature, and short circuit protection. Housed in a 7-lead SOIC package, it operates across a -40°C to 150°C junction temperature range.
- Integrated 700V switch simplifies non-isolated offline designs.
- Supports Buck, Buck-Boost, and Flyback for design flexibility.
- 66kHz switching enables compact, low-cost magnetics.
- Short circuit, open loop, over temperature, and current limiting protection enhance safety.
- Surface-mount SOIC package suits automated assembly.
Non-Isolated Offline Bias Supplies
The LNK305DN-TL integrates a 700V switch for Buck, Buck-Boost, and Flyback non-isolated designs, ideal for direct-coupled bias rails where isolation is not required.
Buck-Boost Auxiliary Rails
Buck-Boost capability lets designers generate rails that may sit above or below the input, useful in appliance and industrial control boards.
Compact Flyback Housekeeping Power
In non-isolated Flyback configuration, the 66kHz switching frequency and 69% max duty cycle support small, low-cost magnetic components.
Home Appliance Control Boards
Short circuit and over temperature protection combined with a -40°C to 150°C junction range make the device suitable for embedded control electronics.
Metering and Sensor Nodes
Current limiting and open loop protection help maintain safe operation in always-on sensing and metering power stages.
