Hello,
I am using LT3840 DC DC converter in my project. but i have one problem that i have used same MOSFET M1 (BSC160N10NS3)and M2 (BSC160N10NS3) in my circuit.
But i have observed shorting in my PCB. Is it possible because of using same MOSFET M1 as in datasheet application note they have mentioned M2(BSC070N10NS3).
And i have checked all the connection in my schematic, and shorting in pcb, and both found ok.

Please suggest some solution of shorting as soon as possible.

Thank u.

Hi,

post
* your schematic (no the datascheet one)
* your PCB layout
* link to both MOSFET datasheets
* link to the LT3840 datasheet

You have chosen different MOSFETs: Did you follow MOSFET selection guide provided in the datasheet?

Also, what is power level? (and Vin and Vout)
Did you take ESD precautions.?

The problem report is very unclear. Are you observing shorted PCB or shorted MOSFET?
