The Power Integrations LNK563PN is a LinkSwitch-LP series isolated flyback offline switcher with an integrated 700V switch, delivering 2.5 W at 83kHz with 70% maximum duty cycle. It offers current limiting, open loop, over temperature, and short circuit protection in an 8-DIP package rated for -40°C to 150°C junction temperatures.
- Integrated 700V switch simplifies low-power isolated flyback designs.
- 2.5 W output suits bias and standby supplies.
- Open-loop and short-circuit protection enhance safety.
- 83kHz switching with 70% duty cycle enables compact magnetics.
- Wide -40°C to 150°C junction range for robust operation.
Low-Power Bias Supplies
The 2.5 W rating and 700V integrated switch make the LNK563PN ideal for auxiliary and bias rails in larger power systems.
Standby Power for Appliances
LinkSwitch-LP series design with open-loop and short-circuit protection supports reliable standby supplies in white goods and consumer electronics.
Metering and Sensor Nodes
The isolated flyback topology provides safe mains isolation for small metering and sensor front-ends drawing minimal power.
Chargers and Adapters
83kHz switching and 70% duty cycle enable compact, low-cost isolated AC-DC conversion for small chargers.
