Hi power led driver

 · When driving high-power LEDs, the power dissipation in a current limiting resistor can make the approach impractical and unattractive. When driving an ultra-efficient lighting source, it is desirable to use a very efficient method. The most efficient way to drive high-current LEDs is to use a DC-DC converter with current www.doorway.ruted Reading Time: 3 mins.  · LUXEON Z ES is a high power mm x mm LED that enables never before seen color consistency, luminance, flux density and design flexibility for lighting solutions. LUXEON Z ES is undomed, a feature that provides unmatched optical Estimated Reading Time: 10 mins. It's more consistent, more efficient, and more flexible. It's ideal for High-power LED's especially, and can be used for any number and configuration of normal or high-power LED's with any type of power supply. As a simple project, i've built the driver circuit and connected it to a high-power LED and a power-brick, making a plug-in light.

High-Power LED Driver with Integrated High-Side LED Current Sense and PWM Dimming MOSFET Driver Flexible HB LED Driver Supports Green Technology for LED Lighting, Display Backlighting, and Display Projection Printable Data Sheet Subscribe Product Details Technical Documentation Design Development Support Training Product Details Parameters. connect to a micro-controller, PWM or a computer! now you've got a fully digital controlled high-power LED light. the micro-controller's output pins are only rated for V usually, that's why the zener diode is important. if your micro-controller is V or less, you need to use circuit #4, and set your micro-controller's output pin to be "open collector" - which allows the micro to pull down the pin, but lets the R1 resistor pull it up to 5V which is needed to fully turn on Q2. if your.
