The LNK6664E from Power Integrations is a flyback offline switcher in the LinkSwitch™-HP series, delivering up to 47 W with a galvanically isolated output. It integrates the power switch and a 650V breakdown rating, operating 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 7-SSIP package with exposed pad, it is rated for -40°C to 150°C junction temperatures.
- Integrated switch reduces external component count and simplifies isolated flyback design.
- 650V breakdown voltage supports robust offline operation.
- Comprehensive fault protection (current limiting, over load, over temperature, over voltage, short circuit) enhances reliability.
- Wide -40°C to 150°C junction temperature range suits demanding environments.
- 120kHz to 136kHz switching frequency enables compact magnetics.
