Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7. I have a old cellphone charger and the schematics is quite similar than yours. Here is the Fairchild’s application note: How reliable is it?
Turn on power triac – proposed circuit analysis 0. Fairchild Semiconductor’s Application Note helped a lot to understand the basics of SMPS design but still the abovementioned part is not clear to me.
Please help me to understand that. Last edited by sunnyimran; 28th July at kde Last edited by avinash. Two in series and current downs to mA.
Also I am working on building a torch using similar LED’s but can’t find a satisfactory battery effecient and brightness effecient solution. The time now is Hi, Here posted is a cheap mobile charger schematics based on power transistor NPNand output is 6.
I noticed that voltage is ksr automatically when i use one, two or three LEDs in series but current passing through LED’s vary with largest current mA when using one LED current is exceeding LED current limit voltage on output terminal is approx 3. We are a bunch of college students doing our miniproject on making a mobile charger. Heat sinks, Part 2: After sometime switch off and again on will give 35 v again with same characteristics.

After searching lot of circuits on net for mains LED driving, I came out with an idea to use my mobile charger from junk. How to optimize the situation, among several options are: Hope you can easily finish your work ‘n post the whole project here.
Can any one help?
