The Power Integrations LNK3208G-TL is an offline AC-DC switcher from the LinkSwitch®-TN2 series in an 8-lead SMD package. It integrates a 725V power switch and supports Buck, Buck-Boost, and Flyback topologies for non-isolated designs. Operating at 66kHz with a 69% maximum duty cycle, it includes Current Limiting, Open Loop, Over Load, Over Temperature, Over Voltage, Short Circuit, and UVLO protection along with Frequency Control and Soft Start.
- 725V integrated switch enables direct offline operation in a compact package.
- Multi-topology support (Buck, Buck-Boost, Flyback) adds design flexibility.
- Broad fault protection set including Open Loop, UVLO, and Over Temperature improves reliability.
- Frequency Control and Soft Start aid stable, controlled startup.
- Wide -40°C to 150°C junction range suits demanding thermal environments.
Non-Isolated Offline Supplies
The LNK3208G-TL's 725V breakdown and integrated switch suit compact buck and buck-boost offline designs without a transformer.
Appliance Control Power
With 66kHz switching and a 69% max duty cycle, it provides efficient low-power bias rails for appliance control boards.
Low-Power Flyback Auxiliary Rails
Flyback topology support enables simple isolated auxiliary supplies where required.
Robust Industrial Designs
