We purchased DC2174A-A to evaluate LTC3882EUJ#PBF. I tried to configured the output voltage by installing the voltage divider resistor. But it seems the default value are still giving the output.
The bit 6 of MFR_CONFIG_ALL_LTC3882 is set to 0 by default (meaning that the LTC3882 will respect the resistor configuration). So if you put a default LTC3882 on your product (or make sure bit 6 of MFR_CONFIG_ALL_LTC3882 is set to 0), yes you can use resistor configuration on VOUT_CFG pins to program the VOUT.
