Our customer have met the following trouble all ADP5052s on ES process now.
After PCB assemble by factory, and power on .
So output voltage is too low voltage.
Ch1 in yellow is supply voltage 12V.
Ch2 /3 in green / blue shows the output voltage.
But after wait for a few minutes, and power on again , so the correct output have comin.
3 times and 4 times also same result.
I put the fail and OK scope pictures here, also enclose the schematic.
Schematic seems good.
Please advice us why this trouble have comin?
