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 ...
Santa Clara, Calif. — National Semiconductor Corp. says it has introduced the industry's first common-anode, current-mode, high-brightness light-emitting diode (LED) driver with pulse-width modulation ...
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 ...
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 ...

What is PWM dimming, and what are the alternatives?
Lots of modern phones use pulse width modulation, or PWM, to manage brightness. But what is PWM, why is it harmful, and what ...
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 ...
