Hallo BroesIk heb de laatste update gedownload. Sindsdien blijf ik elke keer bij het opstarten van de widgets de vraag krijgen of ik de laatste update (die ik al heb) wil downloaden. Hoe kan ik hier van af komen?Mac OS10,5,6

My experience with switch mode linear supplies for LED is rather small, it’s mostly limited by custom solutions. I posted an article about the linear ones because i thought there were many poor uses of high power LEDs with linear supplies on the Internet that could use the information. The range was all the way to dumb connecting of more white LEDs to the 3.3V rail of a computer power supply.
It has been confirmed that my article proved of use to some, at least. Well, my greatest success was to make some people understand why you cannot use a LM317 as a constant mode power supply for a white LED, all powered from 5V.
The switch mode subject is a very vast one, I could only discuss some typical solution. The field of switch mode supplies for LEDs is new and growing, with LEDs proving to be the right solution for lighting of the future. This is why the marked it rather full of products, some better, some trying to cut as many corners as possible in order to reduce the manufacturer costs and providing poor quality for the user.
If i will have time (a resource which seems so poorly available to me lately) I will write an article about driving LEDs with switch mode supplies that involve using hardware on a microcontroller, more exactly I have used PWM and ADC on microcontrollers to make some sort of software switch mode supply for LEDs.

Really nice post. What about non linear power supplies, any experience?
