The LNK6669K-TL from Power Integrations is an isolated flyback offline switcher in the LinkSwitch™-HP family. It integrates a 650V power switch and delivers up to 77 W at 120kHz–136kHz switching frequency with a 64% maximum duty cycle. Protection includes current limiting, over load, over temperature, over voltage, and short circuit. The 12-BESOP package with exposed pad supports thermal management across a -40°C to 150°C junction temperature range.
- Up to 77 W output power for higher-power isolated flyback designs.
- Integrated 650V switch simplifies circuitry and reduces BOM count.
- Full fault protection set improves system reliability.
- -40°C to 150°C junction temperature range for demanding environments.
- 12-BESOP exposed-pad package aids heat dissipation.
Higher-Power AC-DC Adapters
With up to 77 W output in an isolated flyback topology, the LNK6669K-TL suits higher-power adapters and chargers. The integrated 650V switch and 120kHz–136kHz switching frequency support efficient designs.
Industrial and Embedded Supplies
The -40°C to 150°C junction temperature range and full fault protection set (over temperature, over voltage, short circuit, over load, current limiting) make this device suitable for industrial embedded power supplies.
Consumer Appliance Power
Galvanic isolation from the flyback architecture provides safety for consumer appliances, while integrated protection ensures reliable operation under fault conditions.
Auxiliary Power Rails
Up to 64% duty cycle and 77 W capability allow use as an auxiliary supply in larger systems, with short circuit and over load protection for safe fault handling.
