Part Number: TPS62840

Hi,

We have tried usingTPS62840-1DLCEVM55 and it works fine for us. We set the same configuration in our PCB, but the convertor heats up when the input supply is connected. I can share the schematic and PCB layout for review.

  • Hi,

    a schematic and layout would help identifying the issue.

    Without having a schematic and layout, the first things I would recommend you to check are: Input voltage current, output voltage and current, component values (e.g. Inductance of the inductor, capacitors). Also, check if the device is soldered on to the PCB correctly if not already done.

    Best Regards,

    Hi,

    i reviewed the schematic and layout you sent me. If you follow my advice, this should solve the issue.

    Best Regards,
