Turn your 12v adeptor into adjustable Power supply 3V to 20V

hi friends in this video I will show how can you adjust the voltage of a 12V Adaptor to 3 volt to 25 Volts . here they used Externally, the TL431' operation is straightforward. If the voltage on the ref pin input goes above 2.5 volts, the output transistor conducts, causing current flow between the cathode and anode pins. ... Thus, the power supply uses the TL431 to keep the output voltage stable. but here we using A Variable resistor 10K to adjust the voltage from 3volt to up to 20V ( Not recommend more then 15V)

Thank you very much, it's a good deal you have made. Please, there are a few things I didn't understand. - What do you mean by feedback resistor 10 K and to which terminals of the optocoupler must this resistor be connected since these terminals are 1-2-3-4? I asked this question because I have the same adapter, and I want to make like you an adapter with variable voltages. Thank you for responding to my questions.

Find the Upper resistance connected to + Of vcc and replace with 10K resistance and change the output capacitor to 25V Or 35V

Amazing

[@ilonggosubwooferculture928]

Is that only outputs 24Watts max?

[@Electronic_For_You]

Yeas
If you need more power you can use a Laptop charger which can give 40W to 60W

[@bebievillaflor]

is it ok to used this to power my laptop

[@Electronic_For_You]

No
The laptop required 19V and 5A of power.
You should buy a proper laptop Powersupply

Kya isse 4 volt ki 6 led jal jaengi

[@Electronic_For_You]

I didn't understand what you mean

[@stephengiacobozzi7785]

15 v is not 25v

[@Electronic_For_You]

It can go 25V but my Capacitor are rated 16V So I cant go more sorry 😀

Nice
