Hi,
That one runs on steam, right ? ;D

Oh, I forgot:
Here are some datasheets for the nearest brother and for the equivalent one.

Hi, John
I found the info in a book, and now I found it on the net also: http://perso.wanadoo.fr/pouzou/site/composants/sd/2s2000.htm
Good Luck!

Hi mastrila,
Do you have the variac directly between mains and your PSU circuit?
If so is the variac you are using a full transformer model?

A great place for manuals and bulletins covering lots of different equipment: http://www.wimtv.be/techniforum/

Hi mastrila,
If C7 gets hot you probably got oscillation. The only way C7 can get hot is if it -
Must be some [glow=red,2,300]BIG[/glow] crystals if they are used to charge batterys.

Hi gaark.
I have seen a PSU that was equipped with a triac regulation on transformer primary. The way they done it was using a dual potentiometer for the voltage control, not a closed loop. The set-up was about 8 volts difference with no load. I think if you want a closed loop control you have to use a digital potentiometer with -
I believe the filtered output is a necessity because the way switchers work. They shop the current at 40 to 100 kHz (sometimes more) and create spikes and some interference that must be restrained.

Ok, I have missed it then, what is the chip id please?

Go to http://www.doom.com/results_sample.asp and type in SPCA711A.

Hi.
I think C2 and C3:s connections should be as short as possible and be located closer to the regulator.

Sorry. All white led:s I have seen so far are 3.6V drop so 5 Volts will to fine. Unless it was 2.5 V stated in the question instead of 2 - 5 Volts, as I believed.

Why use a chip for this, just a couple of resistors will do the job.

produce electricity using quartz cristals...

Siddhu,
While we are waiting........................
To charge any form of battery there are a threshold for the current/voltage. If there is not enough energy you cannot overcome this threshold and there will be no charging done.
