The LNK3694P from Power Integrations is a Flyback offline switcher in the LinkSwitch™-XT2 series, delivering up to 6 W with a galvanically isolated output. It integrates a 900V power switch and operates at 66kHz with a 65% maximum duty cycle. Fault protection includes current limiting, over temperature, and over voltage. Supplied in an 8-DIP package rated for -40°C to 150°C junctions.
- 900V breakdown rating provides extra voltage margin for high-voltage offline flyback designs.
- Integrated power switch simplifies isolated flyback circuits and reduces external parts.
- Fault protection (current limiting, over temperature, over voltage) improves system reliability.
- 66kHz switching frequency with 65% max duty cycle supports simple transformer designs.
- -40°C to 150°C junction range suits demanding thermal environments.
