Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...

Infineon Technologies is to develop a two-terminal semiconductor device that acts as a circuit breaker for hundreds of volts and amps: doubling the performance of its mains-voltage super-junction ...

A variety of applications use hot-swap controllers, often to increase the reliability of a system. However, a failure in the hot-swap circuit would defeat that purpose. When you use MOSFETs in their ...

As high-brightness LEDs (HBLEDs) penetrate all avenues of the lighting market, various semiconductor manufacturers are offering constant-current drivers. Here's what you need to know before you set ...

The MIC2310 is a single-FET, constant power-limit Hot-Plug controller that Micrel has just released to provide constant power limiting in situations that require safe insertion and removal of PC ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

Having a big block of hot to dump current into is a very useful thing to have if you’re testing batteries, power supplies, high power LEDs, electroplating, or any thing else that would normally ...
