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 ...

Advances in high-power LED technology have increased the importance of thermal aspects in the design phase. To avoid accelerated degradation of output or, worse yet, total failure, LEDs must not get ...

Another important concern is the balance of currents that flow in multiple strings. We know that two or three strings of LEDs will have different combined forward voltages. The LED driver will deliver ...
