LP8863-Q1: EMI/EMC and switching edges adaptation

Quirin Hauf

Part Number: LP8863-Q1

Tool/software:

Hi experts,

It is planned to use the LM8863-Q1 as a driver for LED strings. This should be placed near a GPS antenna.

Are there any test reports or design recommendations regarding the EMI/EMC characteristic?

In addition, the question arose as to whether the LED drivers offer the possibility of softening the switching edges?

Thanks

HI, Quirin

As our device is a controller, the switching edge is controlled by external component.

We could help to review the layout to help do the EMI design.

We have a report for LP8864, pls refer it to below. And is it possible for customer to use LP8866s? It has a detailed guide to pass CISPR25 CLASS 5.
