This file type includes high resolution graphics and schematics when applicable. The circuit in Figure 1 uses a bicolor (red/green) LED to indicate the voltage measured with a set of three color ...

I'm wondering what the generally accepted rules are about what the maximum draw on a motherboard's led connectors is. I'm thinking about hooking up 2-3 leds per function (hdd, pwr, etc) and want to ...

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 ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...
