I am using the MP28167GQ-B in my design to output 12V from the V-bus. I followed the application recommendation in the data sheet for the correct resistor set up to achieve this output, but the device is outputting 22V instead. I reread the datasheet and found I missed the unused I2C lines being tied to the VCC pin so I made that fix*(not shown in the schematic pic, but I made it on the board)*, but the device is outputting 18V now. I have checked several times all of the passive components around the device and everything is correct according to the set up in the data sheet. I have tried replacing the device assuming I got a bad chip and it had the same issues.
Any ideas on a fix or as to what is causing this?
