The Power Integrations LNK302DG-TL from the LinkSwitch-TN series is a non-isolated offline switcher supporting Buck, Buck-Boost, and Flyback topologies. It integrates a 700V power switch, reducing external component count. Operating at 66kHz with 69% maximum duty cycle, it includes current limiting, open-loop, over-temperature, and short-circuit protection. Housed in an 8-SOIC package, it operates across a -40°C to 150°C junction temperature range for compact direct-coupled supplies.
- Integrated 700V switch reduces BOM and board space.
- Non-isolated multi-topology support (Buck, Buck-Boost, Flyback) adds flexibility.
- 66kHz operation with 69% max duty cycle simplifies magnetics.
- Over-temperature and short-circuit protection improve reliability.
- -40°C to 150°C range supports demanding environments.
Non-Isolated AC-DC Rails
