The LNK564PN from Power Integrations is an offline flyback switcher with an integrated power switch and 700V breakdown rating, delivering up to 3 W. Operating at 100kHz with 70% maximum duty cycle, it provides galvanically isolated output in a 7-lead 8-DIP package. Built-in current limiting, open loop, over temperature, and short circuit protection support dependable low-power AC-DC designs across a -40°C to 150°C junction temperature range.
- Integrated 700V power switch reduces external component count and simplifies isolated flyback design.
- 3 W output at 100kHz switching supports compact low-power AC-DC supplies.
- Comprehensive protection (current limiting, open loop, over temperature, short circuit) improves reliability.
- Wide -40°C to 150°C junction temperature range suits demanding thermal environments.
- 7-lead 8-DIP package enables straightforward through-hole assembly.
