series resistor (connected to measure battery current) as shown in Figure 6 to get the actual

output voltage of the non-inverting buck-boost converter.

but the actual output voltage of the converter is equal to:

0.4V (Drop across Sense resistor) = 5.4V.

So we are able to achieve 5.4V from a 5V supply thus validating the concept.
