Buck-boost converters are a form of switching-mode power supply that can supply a regulated DC output from a source voltage either above or below the desired output voltage. This can be particularly ...

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 ...

Boost converters are useful devices for designers because they solve different power issues at low, medium, and high voltages. These issues can occur at any of these voltage levels. A voltage step-up ...

A battery alone may not be capable of supplying complex systems with all the voltage rails necessary to function properly. Applications such as automotive LED drivers, audio amplifiers, and ...

There have been many articles describing the use of multiphase buck converters, especially for high-performance point-of-load applications. However, all the advantages of interleaving, such as higher ...

We have a love/hate relationship with LiIon batteries. They pack all this power in such a small and light package. But for running 3.3 V devices, they’re cumbersome. They need to be stepped down a ...
