The LNK6663V from Power Integrations is a Flyback offline switcher in the LinkSwitch™-HP series, delivering up to 25 W with a galvanically isolated output. It integrates a 650V power switch and operates at 120kHz to 136kHz with a 64% maximum duty cycle. Comprehensive fault protection includes current limiting, over load, over temperature, over voltage, and short circuit. Housed in a 12-SDIP exposed-pad package rated for -40°C to 150°C junctions.
- Integrated 650V switch simplifies isolated flyback designs and reduces external component count.
- Up to 25 W output supports compact AC-DC adapter and bias supply applications.
- Broad fault protection (current limiting, over load, over temperature, over voltage, short circuit) improves system reliability.
- 120kHz to 136kHz switching frequency enables smaller magnetic components.
- -40°C to 150°C junction range suits demanding thermal environments.
