The Power Integrations LNK6666V is a Flyback offline switcher from the LinkSwitch™-HP series with an integrated switch and 650V breakdown rating. It delivers up to 34 W with a 64% maximum duty cycle and operates at 120kHz to 136kHz. Housed in a 12-SDIP package with exposed pad, it provides galvanically isolated output and includes current limiting, over load, over temperature, over voltage, and short circuit protection across a -40°C to 150°C junction range.
- Integrated switch reduces external component count and simplifies isolated Flyback design.
- 650V breakdown supports robust offline operation.
- Comprehensive fault protection improves system safety and reliability.
- Wide -40°C to 150°C junction range suits demanding thermal environments.
- 34 W output with 120kHz to 136kHz switching enables compact power stages.
Industrial Auxiliary Supplies
The 650V breakdown and integrated switch make the LNK6666V well suited to isolated auxiliary rails in industrial equipment, where wide temperature operation from -40°C to 150°C junction is required.
Appliance Power Boards
With 34 W output capability and 64% max duty cycle, this Flyback device supports isolated bias and control supplies in white goods and HVAC control boards.
Metering and Smart Grid Modules
Galvanic isolation and comprehensive fault protection (over voltage, over load, short circuit) help meet safety requirements in energy meters and grid interface electronics.
Standby and Housekeeping Rails
The 120kHz to 136kHz switching range and integrated switch reduce external component count for compact isolated housekeeping supplies in larger power systems.
