My customer asked me the following.
600 mA load applied to the poe output, measured at 620 mA.
This is the reading of the register.
There is a difference from the actual load of the electric loader.
EVboard is measured in the same value as the electric loader.
If you raise the load value a little more, the board is shutdown.
Looking at PCB designs, the difference in current measurement of output in the order that is close to the device decreases slightly.
The circuit diagram is the same as the LTC4270 EVB.
My customer has a strong suspicion of artwork.
Please review the circuit diagram and Artwork.
Also, could you tell me if there is a mandatory in the artwork?
add mandatory in the artwork
