A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...
A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...
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 ...
This article is Part 2 of a new seven-part series on the effects of power quality disturbances on a five-stage electronic LED driver. In Part 1, which ran in the April 2018 issue, we listed seven ...
Lighting-emitting diodes (LED) pervade nearly every electrically operated device, broadly serving functions ranging from power-status display to general illumination. With continuing advances in their ...
