The LNK3206D-TL from Power Integrations is a LinkSwitch™-TN2 non-isolated offline switcher supporting buck, buck-boost, and flyback topologies with a 725V breakdown rating. It integrates the internal switch, switches at 66kHz with 69% maximum duty cycle, and includes current limiting, over temperature, over voltage, and short circuit protection. Supplied in a 7-lead 8-SOIC package rated for -40°C to 125°C junction temperatures.
- Multi-topology flexibility (buck, buck-boost, flyback) supports diverse non-isolated designs.
- Integrated internal switch reduces external component count.
- 725V breakdown voltage provides robust Vds margin for offline operation.
- Built-in current limiting, over temperature, over voltage, and short circuit protection improve safety.
- 66kHz switching with 69% maximum duty cycle supports compact non-isolated supplies.
Non-Isolated Buck Supplies
The buck topology with a 725V breakdown rating and integrated switch makes the LNK3206D-TL well suited to compact non-isolated step-down offline supplies.
Buck-Boost Auxiliary Rails
Buck-boost support enables negative or level-shifted non-isolated rails in control electronics.
Home Appliance Electronics
The -40°C to 125°C junction temperature range supports reliable non-isolated power in appliance control boards.
Smart Switches and Sensors
66kHz switching with 69% maximum duty cycle and short circuit protection suit compact non-isolated power stages.
Metering Front Ends
Over voltage and over temperature protection help ensure safe operation in non-isolated metering supplies.
