TPS99000-Q1: EMC suggestion

David Yang

Part Number: TPS99000-Q1

Hi,

The customer’s application diagram is as below.

When doing EMC testing, the brightness will flicker. It was found that the EMC test hit the connecting cable, causing the brightness to flicker.

Currently, a filter is added on the connector side, but it is ineffective.

Do you have any EMC suggestion for this application?

Thanks & best regards,

Hi,

Do you have any EMC suggestion for this application?

Can flicker caused by EMC be improved by using the Low Bandwidth Sampling function of TIA_PD1 FILT?

How to set it?

Thanks & best regards,

Hi,

Because the customer is currently testing EMC, the problem of the brightness flicker has not been solved.

Are there any solutions you can suggest to customers to improve EMC interference?

Thanks & best regards,
