The Power Integrations LNK614PG is a Flyback offline switcher from the LinkSwitch-II series with an integrated power switch and galvanically isolated output. It offers a 700V breakdown rating, 55% maximum duty cycle, switching up to 85kHz, and delivers up to 4.1 W. Built-in current limiting, open loop, over temperature, and short circuit protection support dependable operation in a compact 8-DIP package rated for -40°C to 150°C junction temperatures.
- Integrated switch simplifies isolated Flyback designs and reduces external component count.
- 700V breakdown rating supports robust mains-connected operation.
- Comprehensive protection suite (current limiting, open loop, over temperature, short circuit) improves reliability.
- Compact 8-DIP package suits space-constrained low-power supplies.
- Wide -40°C to 150°C junction range enables use in demanding environments.
Compact AC-DC Adapters
The LNK614PG delivers up to 4.1 W in a Flyback topology with a 700V integrated switch, making it well suited to small isolated chargers and adapters where board space is tight.
Standby and Auxiliary Supplies
With current limiting, open loop, over temperature, and short circuit protection, this device provides reliable isolated bias power for control circuitry in appliances and industrial equipment.
Home Appliance Control Power
The 8-DIP package and 55% max duty cycle support simple, cost-effective isolated designs for low-power control boards operating across a -40°C to 150°C junction range.
Metering and Sensor Nodes
Galvanic isolation and a 700V breakdown rating let the LNK614PG safely derive low-voltage rails from mains in compact metering and sensor applications.
