The Power Integrations LNK3209D-TL from the LinkSwitch-TN2 series is a non-isolated AC-DC switcher with an integrated 725V breakdown switch. It supports buck, buck-boost, and flyback topologies, operates from an 85V to 265V Vcc supply, and switches at 66kHz with a 69% maximum duty cycle. Frequency control, soft start, and extensive protection including short circuit, open loop, over load, over voltage, over temperature, and UVLO are provided in a 7-lead 8-SOIC package rated for -40°C to 150°C junction temperatures.
- Integrated 725V breakdown switch reduces external component count in non-isolated designs.
- Supports buck, buck-boost, and flyback topologies for design flexibility.
- Extensive protection set (open loop, short circuit, over load, over voltage, over temperature, UVLO) improves reliability.
- Frequency control and soft start simplify stable operation.
- -40°C to 150°C junction rating suits demanding thermal environments.
Non-Isolated AC-DC Bias Supplies
The LNK3209D-TL integrates a 725V breakdown switch, making it suited to compact non-isolated buck and buck-boost bias supplies directly from the AC mains.
Appliance and Home Automation Power
With a 66kHz switching frequency and 69% max duty cycle, it supports small non-isolated power stages in appliances and smart-home devices.
Industrial Control Auxiliary Rails
Rated -40°C to 150°C junction temperature, the LinkSwitch-TN2 device fits auxiliary rails in industrial control equipment.
Robust Fault-Tolerant Designs
Comprehensive protection including open loop, short circuit, over load, over voltage, over temperature, and UVLO improves reliability in non-isolated flyback and buck designs.
