I don't understand clearly! Expecially "impedance of the" etc etc... What mean?If you are using a car battery, the current draw may be limited by the impedance of the circuit connected to its terminals.
My final schematic of SMPS!
An externally hosted image should be here but it was not working when we last tested it.

Just for subwo1..
I've added the cooler for Rectifier's diode... Are them enough?

Ok explain me how i should modify my schematic to make this!I am still wondering if there is a reason you don't want to use the error amp in the SG3524 to control the pulse duration. You might as well just use a multivibrator like a '555 in this application if not.
and perhaps you would like to use the current sense on the LM3524 next. At any rate, here's how to control the pulse width using the error amp.MaXiZ said:

and what about this?
And 2.5V mean that i should regulate the trimer to have 2.5V ad pin1?

What the 2.5V means is that is what you see there when the circuit is regulating correctly after adjusting the potentiometer jackinnj showed you in his circuit. You adjust the potentiometer to get the 37.5V on the B+ output.
The picture you just showed shows the current limit resistor and how it is used. It goes between the sources of the power mosfets and ground.

Do u mean this?if it's caraudio PS then GND primary & secondary must be "ISOLATED" & voltage feedback better be isolated too by opto device.
R12 and A4N35 section?
OR what do u suggest to Isolate Primary GND and Secondary GND?
