Part 2: A 60V buck-boost controller drives high power LEDs, charges batteries and regulates voltage with up to 98.5% efficiency at 100W and higher. Part 3: Offline LED lighting simplified: A high ...

Dimming LEDs is an important feature in many of today’s solid state lighting applications. While many implementations for dimming LEDs in the market today rely on PWM modulation of the LED driving ...

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 ...

With the new driverless AC technology of euroLighting, completely new opportunities open up for the development of LED lighting. The complete circuit with 40W including LEDs fits on a compact 80 x ...
