I'm trying to debug a hardware issue where I am only seeing the feedback voltage on the output of a regulator that is part of a PMIC. The voltage divider that goes into the feedback pin have the correct resistor values. The inductor is properly placed onto the board and the switching frequency looks comparable to the datasheet. I'm thinking that the PMIC isn't properly placed on the board (it's a 48 pin QFN), but the switching pin and feedback pin on the part look like they're properly soldered. Should I use a heat gun and try to reflow the QFN part? Any other ideas? What about replacing the feedback resistors even though they're the appropriate values? I would hope that the issue would be something easy that is going over my head.
Any help is appreciated.
Part I'm referring to is the ADP5052ACPZ-R7, Regulator #4
