MSI motherboards use light-emitting diodes to report the status of the computer. Most computers have an LED for the power and an LED for the hard drive. If the PC is turned on, the power LED glows ...

This project is a simple universal Power LED Driver. The Power LED can be controlled by the built-in PWM signal generator or driven from an external drive signal depending on how the hardware is ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...

I was searching for a LED driver that can also act as dimmer for my 10 watts LEDs and found the PT4115 IC which is kind of interesting. It operates from an input supply between 6V and 30V and provides ...

This file type includes high resolution graphics and schematics when applicable. Light-emitting diodes (LEDs) are semiconductor devices that emit light when an electrical current passes through ...

In Part 1 of this three-part series, we discussed the importance of a well-engineered PCB ground plane for LED drivers, so the ground plane can be effective in managing disturbance energy generated ...
