The Power Integrations LNK305DG-TL is a non-isolated offline switcher from the LinkSwitch®-TN series with an integrated power switch and 700V breakdown rating. It supports Buck, Buck-Boost, and Flyback topologies, switching at 66kHz with a 69% maximum duty cycle. Protection includes current limiting, open loop, over temperature, and short circuit. It is supplied in an 8-SOIC package with 7 leads and operates over a -40°C to 150°C junction temperature range.
- Integrated power switch reduces external parts and simplifies non-isolated designs.
- 700V breakdown voltage supports robust offline operation.
- Flexible Buck, Buck-Boost, and Flyback topologies cover multiple non-isolated applications.
- Comprehensive protection including open loop, over temperature, and short circuit.
- Wide -40°C to 150°C junction temperature range for demanding environments.
Non-Isolated Offline Supplies
The LNK305DG-TL is a non-isolated offline switcher supporting Buck, Buck-Boost, and Flyback topologies. The integrated switch and 700V breakdown rating simplify the primary side.
Buck and Buck-Boost Rails
Supporting Buck and Buck-Boost configurations, the device suits direct-coupled auxiliary rails. A 66kHz switching frequency and 69% max duty cycle provide design headroom.
