Please take advice from electronic hobbyist nearby you. This includes Q1, D1, R3,4,5,6,7 and C2,3,5.

Please do that and see if it will work. Pls sir am happy for this circuit i had a question that can i still remove the 2n transistor if i had no volt drop sir pls i am waiting. Means we have to replace all transistors from Q4 to Q9 by two parallel mosfets irf?? Come join the forum n share your knowledge. So you want datsaheet operation for 24 hrs.
My question is this, what formula do you use for calculating the transformer number of turns and the gauge to use, and even the size of the core, and lamination that can be used, thanks alot, i will be greateful if you will mail me back. Looking for your reply just now. Thank you keep up datasueet good work. However not all of the circuit was explained.
I have read the whole article and really appreciate the fact that it supports error correction. Use either 4x1n general purpose diodes or a bridge rectifier instead. Q2 and Q3 are buffers not to load the IC. It will not be constant in cd circuit.
Hi Prakash all connections shown as ground to be connected to negative of the battery. SG is an integrated switching regulator circuit that has all essential circuitry required for making datadheet switching regulator in single ended or push-pull mode.
Now I can read the parts and now I know something NEW to do with these computors when they work,,which is why I am late responding,mine crashed shortly after my question and now have to use the Libraries to go on line. Datashert for the detailed explanation of how the circuit works, which I have fully understood.
T1 is a standard volt 1 amp transformer 12 VA rating For a VA transformer watts load approx you can calculate datasheeh the above calculations. This error voltage will be proportional to the variation of the output voltage from the desired value and the IC adjusts the duty cycle of the drive signals at pin 14 and 12 in order to bring back the output voltage to the desired value. R11 limits limits the current through the indicator LED D2. Thank for this circult, please sir kindly tell me perhaps this is square waves or sine wave.
Link to the forum is provided on the top of this page.
Does that mean that once a battery triggers it ON, we can remove battery? At oscilator side there are GND at 2N datadheet which line can this be connected.
KA3511DS, KA3524, KA3525
Mujhe ye janna hai k is circuit me 2 transformer kyon use kiye gaye hain? Soon as I connect datxsheet to the transformer, the voltage accross the terminal on my primary drops to 6. It looks compressed because it is a wide diagram and the current theme of the site will just compress it to fit into the content area.
Hi Simeon, thank you!

C8 is a filter capacitor for the voltage regulator IC Hello Ayabami, We have given a detailed description of the circuit and list of components. IC2 and its associated components produce an 8V supply from the 12V source for powering the IC and its related circuitries.
Have you connected you DC supply to Transformer T2 primary center tap. This is replacement for the datashret to mosfet which i design. Kindly expanciate this please:
