The Power Integrations LNK6668V is a flyback offline switcher from the LinkSwitch™-HP series with an integrated switch and galvanically isolated output. It offers a 650V breakdown rating, 47 W power capability, 120kHz to 136kHz switching frequency, and 64% maximum duty cycle. Protection includes current limiting, over load, over temperature, over voltage, and short circuit, packaged in a 12-SDIP with exposed pad rated for -40°C to 150°C junction temperature.
- Integrated switch simplifies flyback design and reduces external parts.
- 47 W power capability supports medium-power isolated supplies.
- 650V breakdown rating provides margin for offline operation.
- Comprehensive protection including short circuit, over load, over temperature, and over voltage.
- 150°C junction temperature rating enables use in thermally demanding environments.
Medium-Power Adapters
With 47 W output capability and a 650V breakdown rating, the LNK6668V suits medium-power AC-DC adapters that require an isolated flyback stage with an integrated switch.
Industrial Power Supplies
A -40°C to 150°C junction temperature range and comprehensive fault protection make this device appropriate for industrial power supplies operating in harsh conditions.
