Sure, you can build an opamp out of a handful of transistors, but why? Just buy an opamp. Same thing here. I’m not suggesting your roll your own buck converter for a commercial design.

In this installment of Circuit VR, we’ll look at a simple buck converter — that is a switching regulator that takes a higher voltage and produces a lower voltage.

All four transistors must switch seamlessly as the converter slews between the buck and the boost modes. The handheld-system market, with its high volumes and good margins, has caused many vendors to ...

But in the 24 to 60V space—comprising industrial, automotive and telecom applications—silicon transistors are not efficient enough to use in multimegahertz buck converters.

Synchronous buck designs can achieve efficiencies over 90%. At these levels, improving performance requires both a good understanding of the sources of power loss and a fanatical dedication to ...

– non isolated buck topology – fast transient capability with narrow regulation band – high level of integration with sophisticated PWM controllers At the same time the availability of integrated ...

GaN Systems announces the availability of its 5MHz buck converter evaluation board (GS61008P-EVBHF) using GaN Systems’ 100V E-Mode GaN transistor and pSemi’s PE29101 integrated high-speed driver ...

Technical Terms Buck Converter: A type of DC–DC converter that steps down voltage by rapidly switching a transistor and utilising filtering elements.

An Introduction to Buck Converter: Working Principle, Advantages And Applications - As electronics become more advanced, the need for efficient power management increases. One crucial element of ...
