Hi Akhila,

Did you try shoring INH/UVLO to VIN? Maybe your divider voltage is too small.

Thanks,

Andrew

Hi,

Yes, I have tried that and also tried by floating INH/UVLO still there is no output.

Thanks,

Hi Akhila,

STSEL is connected to A_VOUT despite there being no SS capacitor. Can you try disconnecting STSEL or adding a soft start capacitor?

Thanks,

Andrew
