The Power Integrations LNK305GN-TL is a non-isolated offline switcher from the LinkSwitch®-TN series with an integrated power switch. It supports Buck, Buck-Boost, and Flyback topologies with a 700V breakdown rating, switching at 66kHz with 69% maximum duty cycle. Protection includes current limiting, open loop, over-temperature, and short circuit. It is offered in an 8-SMD (7-lead) gull-wing package rated -40°C to 150°C (TJ).
- Integrated switch and multi-topology support (Buck, Buck-Boost, Flyback) simplify non-isolated designs.
- 700V breakdown voltage provides margin for offline operation.
- Current limiting, open loop, over-temperature, and short-circuit protection improve reliability.
- 66kHz switching supports compact magnetics.
- Wide -40°C to 150°C (TJ) range for demanding environments.
Non-Isolated Offline Supplies
The LNK305GN-TL provides non-isolated (direct-coupled) Buck, Buck-Boost, and Flyback conversion, making it well suited to cost-sensitive offline supplies where isolation is not required.
Appliance and Lighting Bias Rails
With a 700V breakdown rating and integrated switch, the device supports bias and auxiliary rails in appliances and lighting electronics, reducing external component count.
Small Power Adapters and Controls
Operating at 66kHz with 69% max duty cycle, the LNK305GN-TL enables compact non-isolated designs for control electronics, with current limiting and short-circuit protection enhancing safety.
Industrial Control Nodes
The -40°C to 150°C (TJ) range and over-temperature protection support reliable operation in industrial control and metering nodes using the 8-SMD gull-wing package.
