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.
Standby Supplies
LinkZero-AX series design with open-loop and short-circuit protection supports reliable standby rails in consumer electronics.
Appliance Auxiliary Power
The flyback topology provides safe isolation for bias and control supplies in appliances.
Industrial Sensors
Comprehensive fault protection and -40°C to 150°C junction range support use in thermally demanding sensor enclosures.
