The Power Integrations LNK585DG-TL is a LinkZero-AX series flyback offline switcher with an integrated 700V switch, delivering 4.5 W at 100kHz with 63% maximum duty cycle. It includes current limiting, open loop, over temperature, over voltage, and short circuit protection in a 7-lead 8-SOIC package rated for -40°C to 150°C junction temperatures.
- Integrated 700V switch simplifies low-power flyback designs.
- 4.5 W output at 100kHz enables compact magnetics.
- Comprehensive fault protection (current limiting, open loop, OTP, OVP, SCP) improves reliability.
- 63% maximum duty cycle supports stable regulation.
- Wide -40°C to 150°C junction range for robust operation.
Low-Power Adapters and Chargers
The 4.5 W rating and 100kHz switching frequency enable compact isolated AC-DC designs with the integrated 700V switch.
