DS90UB914A-CXEVM: power supply shorted

Part Number: DS90UB914A-CXEVM

hi,

when i plug the DS90UB914A-CXEVM to 5V-0.3A i see that it is shorted 

any idea where to look 

where can be a fuse or a burned component 

it is brand new yesterday  it was working just fine 

  • Hello, 

    To determine where the board is damaged, you should begin probing all the components starting from the input power supply and probing the outputs of the step down power converters and follow the traces. The User's guide contains the schematic of the board so you should look at the schematic so you know where to begin probing. Find where there may be a short or open and you can determine what component may have gotten damaged and then you can replace that component and test functionality of your board again.

    Thanks
