The LNK6767K-TL from Power Integrations is a LinkSwitch™-HP series offline AC-DC switching IC in Flyback topology with isolated output and an integrated power switch. It offers a 650V breakdown voltage, up to 59 W output power, a 120kHz to 136kHz switching frequency, and a 64% maximum duty cycle. Comprehensive fault protection includes current limiting, over load, over temperature, over voltage, and short circuit. It is packaged in a 12-BESOP (11-lead, exposed pad) and rated for -40°C to 150°C junction temperatures.
- Integrated power switch reduces external components and simplifies the design.
- 59 W output power supports medium-power offline supplies.
- Comprehensive fault protection (current limiting, over load, over temperature, over voltage, short circuit) improves reliability.
- 650V breakdown voltage provides margin for offline mains operation.
- Exposed-pad 12-BESOP package aids thermal performance across -40°C to 150°C.
Isolated Flyback Power Supplies
The LNK6767K-TL uses Flyback topology with galvanic isolation, ideal for offline AC-DC supplies requiring safety isolation. The integrated switch and 650V breakdown rating simplify primary-side design.
Medium-Power Adapters up to 59 W
With 59 W output capability, it suits adapters and open-frame supplies in the medium power range, while the 12-BESOP exposed-pad package aids thermal dissipation.
Designs Requiring Comprehensive Protection
Built-in current limiting, over load, over temperature, over voltage, and short circuit protection help safeguard the supply under fault conditions.
Compact Flyback Designs
A 120kHz to 136kHz switching frequency and 64% maximum duty cycle support compact transformer designs in space-limited enclosures.
Wide-Temperature Applications
Operating junction temperature of -40°C to 150°C supports use in thermally demanding environments.
