The Power Integrations LNK623DG-TL is an isolated Flyback offline switching IC in an 8-SOIC (7-lead) package from the LinkSwitch®-CV series. It features an integrated 725V switch, 54% maximum duty cycle, 100kHz switching frequency, and 9W power rating, with current limiting, open loop, over temperature, and short circuit protection.
- Integrated 725V switch simplifies isolated flyback designs and reduces component count.
- 9W power rating suits compact isolated offline supplies.
- Comprehensive protection (current limiting, open loop, over temperature, short circuit) improves reliability.
- Wide -40°C to 150°C junction temperature range supports demanding thermal conditions.
Isolated Flyback Power Supplies
The LNK623DG-TL uses Flyback topology with galvanic isolation and an integrated 725V switch, ideal for compact isolated offline supplies up to 9W.
Low-Power Adapters and Chargers
With a 9W power rating, 54% maximum duty cycle, and 100kHz switching, it suits small isolated adapters in the LinkSwitch®-CV series.
Robust Protection Designs
Current limiting, open loop, over temperature, and short circuit protection support reliable operation across -40°C to 150°C junction temperature.
Space-Constrained Isolated Designs
The 8-SOIC (7-lead) package with internal switch reduces external components for compact isolated flyback architectures.
