The LNK6778V from Power Integrations is a flyback offline switcher in the LinkSwitch-HP series, delivering up to 47 W with a 725V breakdown rating and an integrated switch. It provides galvanically isolated output, 120kHz to 136kHz switching, and a 64% maximum duty cycle. Comprehensive protection includes current limiting, over load, over temperature, over voltage, and short circuit, in a 12-SDIP package rated for -40°C to 150°C junction temperatures.
- Integrated switch reduces external component count and simplifies flyback design.
- 725V breakdown voltage supports robust offline operation.
- Comprehensive fault protection improves system safety and reliability.
- Wide -40°C to 150°C junction range suits demanding environments.
- Up to 47 W output power covers a broad range of isolated supplies.
