The Power Integrations LNK6665K-TL is a LinkSwitch-HP series isolated flyback offline switcher with an integrated power switch and 650V breakdown voltage. It delivers up to 42 W at a switching frequency of 120kHz to 136kHz with a 64% maximum duty cycle. Fault protection includes current limiting, over load, over temperature, over voltage, and short circuit protection. The 12-BESOP exposed-pad package supports thermal performance across a -40°C to 150°C junction temperature range.
- Integrated power switch simplifies isolated flyback designs and reduces component count.
- 650V breakdown voltage supports robust offline operation.
- 42 W output capability suits medium-power adapters and chargers.
- Comprehensive fault protection including over load and short circuit enhances reliability.
- Exposed-pad 12-BESOP package aids thermal dissipation.
