Tool/software:
Hi Sir,
We found a problem on VIN1 switch to VIN2 when PR1 voltage lower Vref.
The VIN1 is 12V+-10% and VIN2 is 12V+-2%, please check the schematic drawing as below:
Because of we set the VIN1 priority than VIN2, when we plug out VIN1 power source we found sometimes Vout will change to VIN2 then change back to VIN1.
Please check the below picture and we would like to know how to fix this issue?
Yellow line is PR1 pin and green line is Vout.
Thanks,
Ocean
