Buck-boost converter topologies fit into a wide range of applications. Whether you are charging a battery from a battery, powering a string of LEDs, or running a handheld device from a single cell, ...

This course introduces the basic concepts of switched-mode converter circuits for controlling and converting electrical power with high efficiency. Principles of converter circuit analysis are ...

There are standard techniques to generate negative output voltages, and there are well-known approaches to dynamically adjust an output voltage. The missing link that I hope to address in this article ...

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 ...

Linear Technology’s LTC3119 is an efficient, monolithic buck-boost converter that operates with inputs from 2.5 to 18 V (Fig. 1), making it well-suited to operate from one- to four-cell Li-ion ...
