The LNK6665E from Power Integrations is a Flyback offline switcher in the LinkSwitch™-HP series, delivering up to 59 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 7-SSIP exposed-pad package rated for -40°C to 150°C junction temperature.
- Integrated switch simplifies isolated flyback designs and reduces external component count.
- Delivers up to 59 W for higher-power offline applications.
- 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 7-SSIP package aids thermal management.
Higher-Power AC-DC Adapters
The LNK6665E delivers up to 59 W in an isolated flyback topology with an integrated switch, supporting higher-power adapters while reducing external component count. The 650V breakdown rating provides margin for universal AC input.
