Boost power supplies are popular for creating higher dc voltages from low-voltage inputs. As the power demands from these supplies increase, however, a single power stage may be insufficient. This ...

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 ...

Texas Instruments has introduced an IC to mediate between a power rail, a load and a back-up supercapacitor. All the time sufficient voltage is available at the input, the input is connected directly ...

If you need to regulate your power input down to a reasonable voltage for a project, you reach for a switching regulator, or failing that, an inefficient linear regulator. What if you need to boost ...

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, ...

Several bias voltages are needed for supplying and operating an LCD panel. In most cases, specialised integrated circuits with several charge-pumps are used to generate the different voltages. As the ...

Many portable devices use LCD displays. These displays need large positive and negative power supplies, but most mobile devices have power rails at 5 V, 3.3 V or even lower. Thus, the challenge is not ...

[Ludic Science] shows us the basic principles that lie behind the humble boost converter. We all take them for granted, especially when you can make your own boost converter or buy one for only a few ...
