The Power Integrations LNK6664V is a Flyback offline switcher from the LinkSwitch™-HP series with an integrated switch and galvanically isolated output. It delivers up to 28 W at 120kHz–136kHz switching with a 64% maximum duty cycle and a 650V breakdown rating. Comprehensive fault protection and a -40°C to 150°C junction range support robust AC-DC designs.
- Integrated switch reduces external component count in isolated Flyback designs.
- 650V breakdown supports universal offline input margins.
- 120kHz–136kHz switching enables compact magnetics.
- Full fault protection set improves reliability.
- -40°C to 150°C junction range suits demanding environments.
Compact AC-DC Adapters
The LNK6664V integrates the switch and controller in a Flyback topology, delivering up to 28 W for space-constrained adapters with isolated output.
Standby and Auxiliary Supplies
With 650V breakdown and 120kHz–136kHz switching, it suits offline auxiliary rails requiring galvanic isolation.
Industrial Control Power
Operating from -40°C to 150°C junction temperature, it handles demanding thermal environments in isolated Flyback designs.
Home Appliance Power
Built-in over temperature, over voltage, over load, and short circuit protection simplify reliable offline supplies.
