The Power Integrations LNK6667K-TL is an isolated Flyback offline switcher from the LinkSwitch™-HP series with an integrated 650V switch. It delivers up to 59W at a 120kHz to 136kHz switching frequency with a 64% maximum duty cycle. Protection includes current limiting, over load, over temperature, over voltage, and short circuit. It is housed in an 11-lead 12-BESOP package with exposed pad and rated from -40°C to 150°C junction temperature.
- Integrated 650V switch in an isolated Flyback topology reduces external component count.
- Up to 59W output supports higher-power isolated designs.
- 120kHz to 136kHz switching frequency and 64% max duty cycle enable compact magnetics.
- Comprehensive protection (current limiting, over load, over temperature, over voltage, short circuit) improves reliability.
- Exposed-pad 12-BESOP package aids thermal performance; rated to 150°C junction.
