Positive buck-boost
The buck-boost topology fits the application with an input voltage range that overlaps the output voltage, VOUT,
which is the voltage drop across the LEDs and the sensing resistor.
The positive buck-boost (see Figure 26. Positive buck-boost topology ) can provide a positive output voltage,
referred to ground, but it requires two additional power components, a MOSFET and a Schottky diode.
