small switched mode power supplie 400V-12V
Hi, Could some one help me? I am making a project and I need to supplie a PIC from a 400V AC source. I need a small switched mode power supplie and it dont need to be isolated. Is there any solution available for this? Thank you for your pacience Best regards

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
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
