The LNK6779K-TL from Power Integrations is a flyback offline switcher in the LinkSwitch™-HP series delivering up to 77 W with a 725V integrated switch. It operates at 120kHz to 136kHz with a 64% maximum duty cycle and provides galvanically isolated output. Protection includes current limiting, over load, over temperature, over voltage, and short circuit. Housed in a 12-BESOP exposed-pad package rated for -40°C to 150°C junction temperatures.
- Integrated 725V switch simplifies flyback design and reduces external parts.
- 77 W output power supports higher-power isolated AC-DC supplies.
- 120kHz–136kHz switching enables compact magnetics.
- Comprehensive fault protection improves reliability in demanding applications.
- -40°C to 150°C junction range suits industrial and appliance environments.
Higher-Power AC-DC Adapters
Delivering up to 77 W with a 725V integrated switch, the LNK6779K-TL suits higher-power isolated adapters and open-frame supplies using a flyback topology.
Industrial and Appliance Power
The -40°C to 150°C junction range and comprehensive fault protection make this LinkSwitch™-HP device suitable for appliance and industrial auxiliary supplies.
Compact 12-BESOP Designs
