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 ...

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 ...
