The Power Integrations LNK6668K-TL, part of the LinkSwitch™-HP series, is an isolated flyback switcher with an integrated 650V switch delivering up to 68W. It switches at 120kHz to 136kHz with 64% maximum duty cycle and includes current limiting, over load, over temperature, over voltage, and short circuit protection. It is rated for -40°C to 150°C junction temperature in a 12-BESOP exposed-pad package.
- Up to 68W output from an integrated 650V switch flyback, reducing external parts.
- 120kHz to 136kHz switching frequency supports compact transformer designs at higher power.
- Five protection functions including short circuit and over load improve fault tolerance.
- -40°C to 150°C junction temperature rating suits high-thermal-demand applications.
- 12-BESOP exposed-pad package enhances heat dissipation.
