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 ...

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 ...

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 ...

The TPS61094 combines two key benefits here that often demand tradeoffs: the design simplicity of using an integrated buck/boost converter and the extended battery life enabled by high output ...
