The LNK562PN from Power Integrations is a LinkSwitch-LP flyback offline switcher with an integrated 700V power switch, designed for compact isolated power supplies up to 1.9 W. It operates at a 66kHz switching frequency with a 70% maximum duty cycle. Current limiting, open loop, over temperature, and short circuit protection enhance reliability. Supplied in an 8-DIP package with 7 leads, it is rated for a -40°C to 150°C junction temperature range.
- Integrated 700V switch reduces external component count and simplifies design.
- Flyback topology with isolation for safe offline AC-DC conversion.
- Compact 1.9 W output suits low-power bias and standby supplies.
- Comprehensive protection — current limiting, open loop, over temperature, and short circuit.
- Wide -40°C to 150°C junction temperature range for demanding environments.
