How to understand SMPS mobile charger schematics. Hi, Here posted is a cheap mobile charger schematics based on power transistor NPNand output is 6. I’m planning to modify this circuit to get 24v 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. Here is the circuit of the charger: Here is the Fairchild’s application note: Last edited by avinash.
To understand SMPS mobile charger schematics. 130001 simple inverter for flourescent lamps Hi, Many thanks for your post.

We are a bunch of college students doing our miniproject on making a mobile charger. Your diagram is a very good aid in our project.
Hope you can easily finish your work ‘n post the whole project ksw. Hi, I just simulated the ckt from your first post in multisim: But I made the following changes: I have attached several photos of the PCB housing it since I haven’t 130011 a good cam: Originally Posted by vishnu. After searching lot of circuits on net for mains LED driving, I came out with an idea to use my mobile charger from junk.
But that did’nt satisfied me since no good regulation of current through LEDs. I noticed that voltage is adopted 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.
Two in series and current downs to mA. Three in series and current downs to voltage on output terminal is approx 9. How to optimize the situation, among several options are: Also I am working on building a torch using similar LED’s but can’t find a satisfactory battery effecient and brightness effecient solution.

I am planning on 4. Last edited by sunnyimran; 28th July at Ksee will post my matter in a new thread. I have a old cellphone charger and the schematics is quite similar than yours.

Can any one help?
