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. 1. A simple ...

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 ...

Audio amplifiers for high-power portable speakers such as trolley speakers usually operate with lithium-ion batteries, and these batteries can vary from a single cell to a few cells in series.

A buck-boost DC/DC converter is one of the most valuable tools in a power supply designer’s toolbox for dealing with a variety of power conversion scenarios. In these situations, input voltages can ...
