A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition ...

When driving high-brightness LEDs with switching regulators, LED requirements will influence many details of regulator design including the methods used for closing the feedback loop and for LED ...

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 ...

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 ...
