Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...

So why roll your own buck-boost converter for the ground up? Maybe because sometimes the best way to learn is by doing. When it comes to clear and succinct explanations, [GreatScott!] ...

Analogue IC specialist austriamicrosystems has enhanced its DC-DC product portfolio with the introduction of a 200mA boost converter. According to the company, the topology of the AS1337 provides an ...

Known as buck converters if they step the input voltage down and boost converters if they step the voltage up, [Pete] explains how these circuits exploit the properties of an inductor to resist ...

converter or a step-down/up (buck-boost) converter. A buck converter (Figure 1) provides the most efficient solution with the smallest external components, but drops out near 3.3V. At this point, the ...

There's often a need to maintain system voltage at a constant value, whether the battery is charged or discharged; therefore, a single converter is needed to provide both buck and boost operations ...

Maxim Integrated has introduced the Max77827, a buck-boost converter featuring a quiescent current (IQ) of 6µA and peak efficiency of 96%. It addresses the power requirements of low-power wide-area ...
