The Power Integrations LNK6768E is a LinkSwitch™-HP offline flyback switcher with an integrated 650V breakdown power switch. It provides galvanically isolated output up to 135 W at a 120kHz ~ 136kHz switching frequency with 64% maximum duty cycle. Built-in current limiting, over load, over temperature, over voltage, and short circuit protection enhance reliability. Supplied in a 7-SSIP (6 leads, exposed pad, formed leads) package rated for -40°C ~ 150°C (TJ).
- Integrated 650V breakdown switch simplifies isolated flyback designs.
- High 135 W output for demanding offline power applications.
- 120kHz ~ 136kHz switching frequency with 64% maximum duty cycle.
- Comprehensive protection: current limiting, over load, over temperature, over voltage, and short circuit.
- Exposed-pad 7-SSIP package and -40°C ~ 150°C (TJ) range for thermal performance.
High-Power AC-DC Adapters
The LNK6768E delivers up to 135 W in an isolated flyback topology with an integrated 650V breakdown switch, making it suitable for high-power adapters and power supplies. The 120kHz ~ 136kHz switching frequency and 64% maximum duty cycle support efficient transformer design.
