Editors’ Note: This segment is adapted from Chapter 3 of Power Supplies for LED Driving by Steve Winder. We have seen in Chapter 2 that an LED behaves like a constant voltage load with low equivalent ...
Light-emitting diodes (LEDs) 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 ...
Semiconductor junctions — from the millions of transistors used in ICs to the large-area compound junctions that make high-brightness LEDs possible — can all suffer early failure due to increased heat ...
