The LNK304DG-TL from Power Integrations is a non-isolated offline switcher in the LinkSwitch-TN series supporting buck, buck-boost, and flyback topologies. It integrates a 700V switch and operates at 66 kHz with 69% maximum duty cycle. Supplied in a 7-lead 8-SOIC package, it includes current limiting, open loop, over temperature, and short circuit protection across a -40°C to 150°C junction temperature range.
- Flexible buck, buck-boost, and flyback topologies in one non-isolated device.
- Integrated 700V switch eliminates an external power MOSFET.
- 66 kHz switching with 69% maximum duty cycle supports compact magnetics.
- Current limiting, open loop, over temperature, and short circuit protection enhance safety.
- 7-lead 8-SOIC package enables space-efficient board layouts.
Non-Isolated AC-DC Bias Supplies
The LNK304DG-TL supports buck, buck-boost, and flyback topologies in a non-isolated configuration, making it suitable for direct-coupled bias rails in appliances and controls.
Low-Power Buck Converters from AC Line
With a 700V integrated switch and 66 kHz switching, this LinkSwitch-TN device enables compact step-down supplies without a transformer.
Buck-Boost Auxiliary Rails
The buck-boost capability allows generation of negative or level-shifted rails for metering and motor control electronics.
Space-Constrained 8-SOIC Designs
The 7-lead 8-SOIC package and 69% maximum duty cycle help shrink board area in non-isolated offline designs operating from -40°C to 150°C.
