The LNK576DG-TL from Power Integrations is an isolated flyback offline switcher in the LinkZero-LP series, delivering up to 9 W. It integrates a 700V power switch, operates at 100kHz with 63% maximum duty cycle, and includes current limiting, open loop, over temperature, over voltage, and short circuit protection. Housed in a 7-lead 8-SOIC package rated to 150°C junction temperature.
- Integrated 700V switch reduces external component count and simplifies isolated flyback design.
- 9 W output at 100kHz supports compact, efficient low-power adapters.
- Comprehensive fault protection (current limiting, open loop, OVP, OTP, short circuit) improves reliability.
- -40°C to 150°C junction range enables use in demanding thermal environments.
- Space-saving 7-lead 8-SOIC package suits dense PCB layouts.
Compact AC-DC Adapters
The 9 W power rating and 700V integrated switch make the LNK576DG-TL ideal for small chargers and wall adapters where board space is tight and isolated flyback topology is required.
Standby Power Supplies
Part of the LinkZero-LP series, this device suits auxiliary and standby rails in appliances and consumer electronics needing isolated, low-power conversion.
Home Appliance Control Boards
With -40°C to 150°C junction rating and comprehensive fault protection, it reliably powers control logic in white goods and HVAC systems.
Industrial Auxiliary Rails
The 700V breakdown voltage provides margin for universal AC input, while current limiting and over temperature protection safeguard isolated low-voltage bias supplies.
IoT and Smart Home Devices
Compact 8-SOIC package and integrated switch simplify isolated power design for connected sensors and smart plugs.
