TPS54360: Failed CE due to Conducted Emission.

Pang

Part Number: TPS54360

Hi Ti,

I am usin TPS54360 with Vin: 24V and Vout: 0V ~ 16V output@1A and the feedback, I have add a potentiometer to replace the resistors in voltage divider at 50KOhm to adjust the output voltage from 0V ~16V and find that there's conducted EMI.

Please help to advise on resolving it.

Hi Electrobud,

Can you share the part number of the freewheeling diode and the input capacitor.

Thanks and Regards,

Hello,

Typically Conducted EMI will require an in input filter to attenuated noise generated by a switching power supply.

Please see link below of a paper that will help you select a filter and design correctly to meet your EMI needs.
