The Power Integrations LNK6666K-TL from the LinkSwitch-HP series is an isolated flyback offline switcher with an integrated 650V switch. It delivers up to 48 W at 120kHz to 136kHz switching frequency with a 64% maximum duty cycle. Housed in a 12-BESOP package with exposed pad, it includes Current Limiting, Over Load, Over Temperature, Over Voltage, and Short Circuit protection across a -40°C to 150°C junction range.

  • Integrated 650V switch reduces external component count in flyback designs.
  • 48 W output power supports medium-power isolated AC-DC applications.
  • 120kHz to 136kHz switching enables compact transformer sizing.
  • Comprehensive fault protection improves system reliability.
  • Exposed-pad 12-BESOP package aids thermal dissipation.

Medium-Power AC-DC Adapters

Delivering up to 48 W with a 650V integrated switch, the LNK6666K-TL suits laptop and appliance adapters needing isolated flyback conversion.

Industrial Power Supplies

The -40°C to 150°C junction temperature range supports reliable operation in demanding industrial environments.

Consumer Electronics Chargers
