Turning a Fixed Voltage Adapter into a Variable Output Power Supply (3v-25v)

[@zaneenaz4962]

nicely done. some more explanation of the comparator....but we can figure that out. Thanks

My adapter has an IC with six legs,not the same(its so tiny that specifications dont even exist),what do I do in this case,how shall I detect the resistor to pull out??..Nice video and work by the way..thank you in advance

@@Electricquantism402 I dont even know..but the coupler on the other side of the board writes on it: "EL 817 C024",if thats a useful clue...

Will it give the same ampere as before after converting it? If it was a 19 v 3A default will it still give 15v 3A after converting?

[@Electricquantism402]

For compensation of 65w power, it increases the current when voltage is decreased.

@@Electricquantism402 even better, hope it won't over work the switching driver. But yeah Thank you for that. Looking forward for more videos in your channel.

Why did you choose resisters in series and left other

[@Electricquantism402]

Mentioned that its directly connected to inverting input pin which controls the feedback depending upon its resistance between output and inverting input pin..

[@arishimran2206]

@Electricquantism402 and wasn't connection of single resistance the same

👍👍but: How to open such a sealed housing without damaging......

[@Electricquantism402]

Apply thinner and wait for a while, then open. Or use small hammer and smash from all sides by placing the housing on floor..

Hello, I have a strange problem with modification of the adapter. I can make the voltage adjustable but when I touch the metal of the potentiometer the voltage goes to zero and I have to restart the adapter. It happens each time. When I try to use different potmeter or resistance the adapter will try to start but stops directly.

[@Electricquantism402]

Which IC is in your adapter?

[@ElectronicBlood]

I have many of them

[@Electricquantism402]

Good.. enjoy by converting them.👍👍

Ampier loss 😢 so only voltage

Acha

[@LP-yd4ww]

Resistor is ?? Kohm.

[@Electricquantism402]

Yes..8.06Kohm which is default resistor.

[@MonkeyBlueAss]

removed resistor in 8.06Kohm and the new resistor is 1k in series with the potentiometer
