Part Number:TPS51120
Hi,
I am using a TPS51120 to give a 5V and a 3V3 to my system from an unregulated voltage (12-24V). I observe a lot of electromagnetic disturbances
(radiated for sure, conducted maybe) and it seems that they come from the TPS51120. I think I have followed correctly the datasheet to sizing components,
so is there additional filters (input filter for example) or something to check particularly to reduce disturbances ? I haven't done the routing myself but I don't see
aberrant mistakes. I am using the TPS51120 in current mode, output max 8A, 580Khz for 3.3V an 380khz for 5V.
Thanks
