The LNK304GN-TL from Power Integrations is a LinkSwitch-TN offline switcher IC with an integrated 700V power MOSFET for non-isolated Buck, Buck-Boost, and Flyback designs. It switches at 66kHz with a 69% maximum duty cycle and includes current limiting, open loop, over temperature, and short circuit protection. Housed in an 8-SMD (7-lead) gull-wing package, it operates across a -40°C to 150°C junction temperature range.
- Integrated 700V MOSFET simplifies design and reduces external parts.
- Supports Buck, Buck-Boost, and Flyback topologies for versatility.
- Open loop, over temperature, current limiting, and short circuit protection.
- 66kHz switching with 69% max duty cycle for compact magnetics.
- Wide -40°C to 150°C junction temperature range for harsh environments.
Appliance Control Bias Supplies
The LNK304GN-TL provides a non-isolated bias rail for white goods and small appliances. Its integrated switch and 700V breakdown rating enable direct offline operation with few external parts.
Buck Converter Low-Voltage Rails
In Buck topology, this LinkSwitch-TN device steps down the AC mains to logic-level rails. The 66kHz frequency and 69% max duty cycle keep the magnetic components compact.
Buck-Boost for Flexible Output
Buck-Boost topology lets the output sit above or below the input, useful for wide-range auxiliary supplies. Open loop and short circuit protection guard against fault conditions.
Flyback for Non-Isolated Loads
For simple non-isolated flyback designs, the LNK304GN-TL integrates switch and control, cutting BOM cost while retaining over temperature protection.
High-Temperature Environments
With a -40°C to 150°C junction temperature range, the device suits thermally demanding applications in industrial and outdoor electronics.
