Should I use an inverting buck-boost or a positive buck-boost topology?
Input voltage range = 19-22VDC, Output voltage range = 10-56VDC, Application = LED driver
The app not I have says the inverting topology fits applications with an input voltage range that overlaps the output voltage, and that the positive buck-boost supports applications where the input voltage range crosses the output voltage.
I feel like with those descriptions either topology would work. Although, the input voltage doesn't exceed the output voltage. Which one would be better?
