The LNK613PG from Power Integrations is an isolated Flyback offline switcher with an integrated 700V switch. Part of the LinkSwitch-II series, it delivers up to 3.3 W at switching frequencies up to 85kHz with a 55% maximum duty cycle. Housed in an 8-DIP 7-lead package, it includes current limiting, open loop, over temperature, and short circuit protection across a -40°C to 150°C junction temperature range.
- Integrated 700V switch simplifies isolated Flyback designs and reduces external parts.
- Galvanic isolation provides safety separation between input and output.
- Current limiting, open loop, over temperature, and short circuit protection enhance reliability.
- Up to 85kHz switching frequency supports compact transformer designs.
- Wide -40°C to 150°C junction temperature range suits demanding thermal environments.
Isolated Low-Power Bias Supplies
The Flyback topology and galvanic isolation make the LNK613PG well suited for isolated bias rails. The integrated 700V switch and up-to-85kHz switching frequency support compact transformer designs within the 3.3 W power envelope.
Chargers and Adapters
With a 55% maximum duty cycle and integrated switch, this device supports small isolated power supplies. Current limiting and short circuit protection help maintain safe operation under fault conditions.
Standby and Auxiliary Rails
Isolated auxiliary rails benefit from the Flyback configuration, which provides galvanic separation between input and output. Over temperature protection adds robustness in enclosed designs.
Industrial Control Bias
The -40°C to 150°C junction temperature range supports use in demanding thermal environments. Open loop protection guards against feedback faults in isolated control circuitry.
