The LNK6664K-TL from Power Integrations is a Flyback offline switcher in the LinkSwitch™-HP series, delivering up to 39 W with a galvanically isolated output. It integrates a 650V power switch and operates at 120kHz to 136kHz with a 64% maximum duty cycle. Fault protection includes current limiting, over load, over temperature, over voltage, and short circuit. Packaged in a 12-BESOP exposed-pad format rated for -40°C to 150°C junctions.
- Integrated 650V switch simplifies isolated flyback designs and reduces external components.
- Up to 39 W output supports higher-power AC-DC adapter applications.
- Broad fault protection (current limiting, over load, over temperature, over voltage, short circuit) improves reliability.
- 120kHz to 136kHz switching frequency enables compact magnetic designs.
- -40°C to 150°C junction range suits demanding thermal environments.
