The LNK3205D-TL from Power Integrations is a LinkSwitch™-TN2 offline switcher with an integrated power switch for compact non-isolated AC-DC conversion. It supports Buck, Buck-Boost, and Flyback topologies with a 725V breakdown rating, 69% maximum duty cycle, and 66kHz switching frequency. Current limiting, over temperature, over voltage, and short circuit protection are built in. The 8-SOIC package and -40°C to 125°C junction range suit space-constrained designs.
- Integrated power switch reduces external component count and simplifies non-isolated offline designs.
- 725V breakdown voltage provides robust margin for mains-connected operation.
- Multi-topology support (Buck, Buck-Boost, Flyback) enables design reuse across applications.
- Comprehensive fault protection (current limiting, over temperature, over voltage, short circuit) improves system safety.
- Compact 8-SOIC package with -40°C to 125°C junction range suits space-constrained designs.
Non-Isolated Bias Supplies
The LNK3205D-TL's Buck topology and 725V breakdown rating suit non-isolated bias supplies that derive low-voltage rails directly from offline mains without a transformer.
Appliance Housekeeping Power
With an integrated switch, 66kHz switching frequency, and 69% duty cycle, this device provides compact, reliable housekeeping power for appliances where cost and board space matter.
Buck-Boost Auxiliary Rails
Buck-Boost support enables negative or level-shifted auxiliary rails for metering and industrial control front-ends needing a simple non-isolated conversion stage.
Compact Flyback Stages
When a small flyback stage is required, the integrated switch and fault protection (current limiting, over temperature, over voltage, short circuit) simplify implementation.
