The LNK304DN-TL from Power Integrations is a LinkSwitch®-TN non-isolated offline switcher supporting buck, buck-boost, and flyback topologies with a 700V breakdown rating. It integrates the internal switch, switches at 66kHz with 69% maximum duty cycle, and includes current limiting, open loop, over temperature, and short circuit protection. Supplied in a 7-lead 8-SOIC package rated for -40°C to 150°C junction temperatures.
- Multi-topology flexibility (buck, buck-boost, flyback) supports diverse non-isolated designs.
- Integrated internal switch reduces external component count.
- 700V breakdown voltage provides robust Vds margin for offline operation.
- Built-in current limiting, open loop, over temperature, and short circuit protection improve safety.
- Wide -40°C to 150°C junction temperature range for demanding environments.
Non-Isolated Buck Supplies
The buck topology with a 700V breakdown rating and integrated switch makes the LNK304DN-TL ideal for compact non-isolated step-down offline supplies.
Buck-Boost Auxiliary Rails
Support for buck-boost operation lets designers generate negative or level-shifted rails in non-isolated control electronics.
Home Appliance Electronics
The -40°C to 150°C junction temperature range supports reliable non-isolated power in appliance control boards.
LED and Sensor Drivers
66kHz switching with 69% maximum duty cycle and short circuit protection suit simple non-isolated driver stages.
Metering and Smart Switches
Current limiting and over temperature protection help ensure safe operation in compact non-isolated power stages.
