UCC12040: EMI radiation data

Part Number: UCC12040 Team, Do we have EMI measurements of how the UCC12040 behaves? A customer of mine would like to see some real measurements done on a reference board. Thanks, Robert

Hi Robert, I will need to ask my colleagues in the US. I hope to have a response later today. Regards Peter

Hi Robert, I have attached for the UCC12050 which will have the same behaviour as the UCC12040.

Thanks Peter! But there is an additional question. In All 30-1000MHz Magneto SSM2Layer 50 ohm Load_Graph_Horizontal.pdf the first peak at 38.23 MHz is only 5 dB below the limit. Looks like a 50 Ohm resistive load was used. Would be better to use an 'artifical Hand' (220pF + 510Ω) to GND, as this is what regulations like EN 60601-1-2 ask for. Do we also have such measurements? Best regards, Robert

Hi Robert, That is all that we have, I will feed your comments back to the team it looks like EN 60601-1-2 is targeted to medical devices, I think the team are probably focused on the industrial market in the first instance so the requirements may be different. How much margin are you looking for from the limit line? Regards Peter
