Malvern, Penna.&#8212Vishay Intertechnology's two new white LED drivers, the SiP12401 boost controller and SiP12501 boost converter, are optimized for backlighting small liquid crystal displays in ...

LEDs are finding their way into more products than ever before. Automotive lighting, TV backlights and tablets are just a few applications that require multiple LEDs. Driving a large number of LEDs ...

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.

With the holiday season now here, it’s time to think about putting those Christmas lights up. These festive decorations don’t don’t stay on our homes forever, and we wanted to take it upon ourselves ...

Sponsored by Digi-Key and Infineon Technologies: Today’s lighting systems are dominated by LED technology. Though it seems a relatively simple concept, lighting multiple LED arrays requires special ...

Light-emitting diodes are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the constant-current ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

[Henryk] just sent us his latest episode of simple LED circuit puzzles. In front of the camera he solders one pin of each of the 3 LEDs to a different switch. He then puts the three assemblies in his ...

Kriya Therapeutics has closed an oversubscribed Series D funding round, raising $320m, aimed at propelling its gene therapy ...
