How to Use a Multiphase Boost Converter (Download)
Switch-mode power supplies (SMPS) based on the boost principle can convert a low voltage into a higher voltage. For this purpose, the standard boost topology is used as shown in Figure 1.
This topology ensures that the output side receives pulsed currents from the inductor. However, since a voltage converter requires a fixed output voltage, output capacitor C2 has an important task. The capacitor must average the pulsed currents into a fixed output voltage.
