Tool/software: WEBENCH® Design Tools
A design use the tps53647 to output 3.3V @ 100A.
The schematic is designed by the webench except the Output Voltage Scaling resistor.
I use 16pcs 2.5ohm Cement Resistors as the load.

when I power up the tps53647 board, the output doesn't work .
It seems like the 3v3 output is over current protected( the up pic.)
I remove the Output Voltage Scaling resistors. The output is 1.66V.
I remove all the Cement Resistors, add the Output Voltage Scaling resistors, the output is 2.8V.
How to use the Voltage Scaling resistors to output 3.3V with tps53647. Could you Review the Sch? Thanks!
