"ADP3050 Buck Regulator Design Tool" can not design the ADP3050 in a buck-boost configuration that produces a negative output voltage from a positive input voltage.
In the datasheet 18 page, "INVERTING (BUCK BOOST) REGULATOR"
The circuit in Figure 29 shows the ADP3050 in a buck-boost configuration.
For example, following output setting is available for ADP3050?
IOUT:0.5~1A ;need to set less current ?
