Hi,

i have a problem with this IC.

I attached the schematic.

When i try to turn on the device, at the output i not see anything.

I only see peak between the off interval.

Thanks

    Hello Marco,

    I don't see any issues with the schematic really except perhaps R36. I am not sure if that is the default in webench, but in real circuits I have seen high value resistors between VCC and IADJ cause enough drop that IADJ is nearly zero. Before we can determine if there is something else wrong please short R36 and connect IADJ directly to VCC as recommended in the datasheet and see if that solves the issue.

    Thanks,

    Clint
