    Hello,

    To enhance EMI performance, the layout is a very important step. Firstly please see datasheet layout guideline part. Place output capacitor C43, C41, C42 very close to the IC. Secondly RC snubber is suggested to put at SW to ground to decrease spikes during switching on and off. Thirdly, inductor bead could also be added at output.
