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 ...

Last spring, in response to California's recent electricity shortage, Governor Gray Davis signed a bill into law that provides financial incentives for upgrades that improve the efficiency of motor ...

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 ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...

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 ...
