Thanks LucaV,
I think the layout precautions are taken as you mentioned. But i will try to send you some snapshots of the layout. It will be tough to send the complete board layout. Is there an email ID i can use to send you the design ?
Also i am using XFL4020-472 Coilcraft at 4.7uH. I see that an XAL series is recommended for higher Isat with minor penalty on DCR. Our continuous current draw at 5.6V is 1.5A. I can try switching to the XAL series. What would you recommend ?
Thanks again,
AB
