In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED lighting’s many advantages simply cannot make up ...

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 ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

International Rectifier’s IRS29831 LEDrivIR integrates an LED driver controller and a 700-V MOSFET optimized for single-stage flyback and buck-boost topologies used in LED drivers, including LED bulb ...

There are many applications for LED lighting, from simple incandescent or CCFL lamp replacement to new opportunities in architectural, industrial, medical, and other applications. Each of these ...

Cold-cathode fluorescent display backlights are compared/contrasted to LED backlights, and the differences in driver circuits for both are discussed. CCFL backlights are the most common backlight ...

Analog dimming of LEDs has key advantages, including standalone operation, without the need for additional circuitry to generate a PWM signal (such as a microcontroller) and a patent-free environment.
