The LNK3207D-TL from Power Integrations is a multi-topology offline switcher in the LinkSwitch®-TN2 series supporting Buck, Buck-Boost, and Flyback configurations with non-isolated output. It features a 725V breakdown voltage rating, integrated switch, 66kHz switching frequency, and 69% max duty cycle. Control features include EN, frequency control, and soft start, with current limiting, over temperature, over voltage, and short circuit protection in an 8-SOIC package rated for -40°C to 150°C junction temperatures.
- Multi-topology flexibility (Buck, Buck-Boost, Flyback) for varied designs.
- Integrated switch reduces external component count.
- 725V breakdown voltage supports robust offline operation.
- Soft start and frequency control improve startup and stability.
- Wide -40°C to 150°C junction range suits demanding environments.
