H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system battery drops to lower voltages. They make sense when a single-stage ...

The circuit shown in Figure 1 illustrates one of the most basic versions of the buck-boost voltage regulator. An electrical switch is connected in series with the line input to regulate the circuit.

In many applications, voltages require upward and downward conversion. One example would be if an input voltage range of 6 to 24 V is available, and 12 V would be generated from it. Classical ...
