Using a boost regulator to drive high-brightness (HB) LEDs requires a change in design philosophy for almost every component, including the control loop compensation. This paper explains the reasons ...

As the results show, the Spectre Pro PWM series delivered underwhelming performance. They were consistently the weakest performing and near-loudest fans in all our testing. They look good and they ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

Machine-vision systems use very short flashes of intense light to produce high-speed images employed in a wide variety of data-processing applications. For instance, fast-moving conveyor belts are run ...
