The LNK3205G-TL from Power Integrations is a multi-topology offline switcher in the LinkSwitch-TN2 series, supporting buck, buck-boost, and flyback configurations with non-isolated output. It features a 725V breakdown rating, an integrated power switch, 66kHz switching frequency, and 69% maximum duty cycle. Protection includes current limiting, over temperature, over voltage, and short circuit. It is supplied in an 8-SMD (7 leads) gull-wing package rated for -40°C to 125°C junction temperature.
- Flexible buck, buck-boost, and flyback topologies in one device.
- Non-isolated direct-coupled output reduces component count and cost.
- Integrated switch simplifies compact AC-DC designs.
- 725V breakdown rating supports universal offline input.
- Built-in current limiting, over temperature, over voltage, and short circuit protection.
Non-Isolated AC-DC Supplies
The LNK3205G-TL supports buck, buck-boost, and flyback topologies with non-isolated output, making it flexible for direct-coupled low-power AC-DC designs.
