The Power Integrations LNK3209GQ-TL is a LinkSwitch-TN2Q offline switcher integrating a 750V, 850mA switch in an 8-SMD gull-wing package. It supports buck, buck-boost, and flyback topologies with either isolated or non-isolated output, operating at 66kHz with a 70% maximum duty cycle. Frequency control, soft start, and full fault protection make it a versatile choice for compact offline power designs.
- Integrated 750V, 850mA switch reduces external component count and simplifies design.
- Supports buck, buck-boost, and flyback topologies for design flexibility across applications.
- Frequency control and soft start improve startup behavior and operating stability.
- Comprehensive protection including short circuit, over load, over temperature, and over voltage enhances reliability.
Non-Isolated Buck Supplies
The integrated 750V switch enables direct offline buck conversion for low-power bias and housekeeping rails without a transformer.
Buck-Boost Conversion
Buck-boost topology support allows output voltages above or below the rectified input, useful for wide-range auxiliary supplies.
Isolated Flyback Designs
When isolation is required, the same device supports flyback operation, offering design reuse across multiple product variants.
Appliance and Industrial Controls
Soft start, frequency control, and comprehensive fault protection (including short circuit) support reliable operation in appliance and industrial control boards.
