- W2894636410 abstract "An LED driver is an electrical device that helps in the regulation of power to an LED or to an array of LEDs. The LED driver adapts to the requirements of the LED, by supplying a continuous quantity of power to the LED when its electrical properties vary. LEDs are as a matter of fact sensitive to the voltage used to power them (i.e., the current changes a lot with a little change in voltage). To avert the LED from becoming unstable due to voltage changes, an LED driver is necessary. An LED driver is a self-contained power supply which has outputs that are affianced to the electrical characteristics of the LED or to the array of LEDs. LED drivers may offer to dim by means of pulse width modulation circuits and may have different channels for separate control of different LEDs or LED arrays. Without the most suited driver, the LED may become hot and unstable, therefore, cause poor performance or failure. This paper presents a novel approach to the design of a LED Driver using various power transistors, power MOSFETs, operational amplifier and feedback circuits. The experimental results demonstrate the power delivered to the LED at different supply voltages upholding the performance of the driver circuit proposed." @default.
