About TPS54528 audio noise issue

Other Parts Discussed in Thread: TPS54528

Hi Sir,

My customer simulate TPS54528 on TI's EVM board, but have one issue, at 20mA load occur audio noise, source from inductor, waveform as below FIG.

Green is current

Blue is PWM



Currently increase inductance from 3.3uH change to 10uH, can solve this issue, i know this method can decrease peak current, so I also need attention what parts impact performance?

if you have better solution, please advise me, thanks.
