TPS23756EVM: Conducted Emission

Part Number: TPS23756EVM

Hi,

We have tested our custom PoE PD device circuit for conducted emission test. We followed the schematic of TPS23756EVM and as comparing with the EVM conducted emission result provided in the EVM user guide, our system having more conducted emissions especially in the lower frequencies (150khz to 1 MHz). Kindly suggest a solution to overcome this situation. Resulting graph, schematic diagram are attached herewith for your reference
