I am assuming you mean 400VDC input and 12V output low power. If so then please refer to data sheet and associated app note for LNK-TN series

Hi, thank you for your asnwer.

In fact is a 400V AC and maybe I saw it wrong but ins't the LinkSwitch-TN limited to 265 VAC?

If you click on Applications section at top of our website front page you will see a drop down list and at bottom is utilities/smart meters. Click on that and there you find a report: (Three Phase Utility Meter Ultra-Wide Input (3 W 12 V / 250 mA. this will show you how you can extend voltae rane by adding a MOSFET
