You can fade out and fade in the light of an LED automatically by using Arduino and a simple code that is described below. Even though the Arduino board cannot output variable voltage on its digital ...

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 ...

This article is a design example report of a 6.5 W, low-line input, non-dimmable, non-isolated buck LED driver employing LYTSwitch™-1 LYT1603D. It normally operates at input voltage ranging from 90 ...

Most small-size color LCD displays today use white LEDs for backlighting. These systems usually involve handheld devices with an LED drive circuit powered by a battery whose output voltage varies over ...
