The LNK6665V from Power Integrations is a Flyback offline switcher in the LinkSwitch™-HP series, delivering up to 30 W with a 650V breakdown rating. It integrates the power switch for a galvanically isolated output, operates at 120kHz to 136kHz with 64% maximum duty cycle, and includes current limiting, over load, over temperature, over voltage, and short circuit protection. Housed in a 12-SDIP exposed-pad package rated for -40°C to 150°C junction temperature.

  • Integrated switch simplifies isolated flyback designs and reduces external component count.
  • 650V breakdown voltage provides margin for universal offline input.
  • Comprehensive fault protection (current limiting, over load, over temperature, over voltage, short circuit) improves reliability.
  • Wide -40°C to 150°C junction temperature range supports demanding environments.
  • Exposed-pad 12-SDIP package aids thermal management.

AC-DC Adapters and Chargers

The LNK6665V delivers up to 30 W in an isolated flyback topology, making it well suited to compact external power adapters. Its integrated switch reduces external component count while the 650V breakdown rating provides margin for universal AC input.

Standby and Auxiliary Supplies

With 120kHz to 136kHz switching and a 64% maximum duty cycle, this LinkSwitch-HP device supports efficient auxiliary rails. Comprehensive fault protection including over load and short circuit safeguards the supply during abnormal conditions.

Industrial Control Power

Operating from -40°C to 150°C junction temperature, the LNK6665V suits industrial environments. The 12-SDIP exposed-pad package aids thermal dissipation in space-constrained designs.

Home Appliance Power

Isolated flyback operation with integrated switch simplifies offline power design for appliances, while over temperature and over voltage protection support reliable long-term operation.
