The LNK3208P from Power Integrations is a LinkSwitch®-TN2 offline switcher supporting buck, buck-boost, and flyback topologies in a non-isolated configuration. It integrates a 725V power switch, operates from an 85V to 265V supply, switches at 66kHz with 69% maximum duty cycle, and includes frequency control and soft start. It is offered in a 7-lead 8-DIP package.
- Integrated 725V switch simplifies non-isolated offline designs.
- Supports buck, buck-boost, and flyback topologies.
- Comprehensive protection including short circuit, over load, and UVLO.
- Frequency control and soft start for controlled operation.
- Wide -40°C to 150°C junction temperature range.
Non-Isolated Buck Supplies
The LNK3208P integrates a 725V switch for non-isolated buck conversion, ideal for direct-coupled low-power offline supplies.
Buck-Boost Designs
Support for buck-boost topology enables step-up/down non-isolated rails from offline input using the integrated switch.
Compact Flyback Configurations
Where a flyback arrangement is used, the integrated switch and 66kHz switching simplify the power stage.
Robust Protection
Current limiting, open loop, over load, over temperature, over voltage, short circuit, and UVLO protection safeguard operation.
Harsh-Environment Boards
A -40°C to 150°C junction temperature range suits demanding thermal environments.
