hi,

The question from kiprono meant your input voltage is AC or DC into the psu?

Putting it otherwise, you operate it from the mains or from a DC source?

In case you feed it from the mains, here is a circuit for a linear psu:

If you do not have 120V AC mains voltage in your country but have 220-240V, then the transformer T1 should be chosen accordingly.

If you wish to build a switch mode power supply instead of the above linear one, here is one possibility out of many:

**broken link removed**

In this case the input voltage should be any DC between 5V - 36V and efficiency is over 90% or so, no need for big heat sink area, unlike in case of the above linear psu circuit. (So any mains transformer of 10V-24V AC output @5A with rectifier bridge and a suitable puffer cap should do.)

Here are some other choices for switch mode ICs you can choose from, of course other manufacturers are also an option:

@ibrahim_mo

In my links I referred to useful circuits. I cannot help with even more useful circuits, those are just the useful ones for your problem. You need further study in this psu topic, I wish you good luck.

iam sorry
i read your topic but my input is 4A and i need the output is 5A
your circit is 5A in and 5A out

I do not understand where you take the 5A in and which circuit do you mean exactly??

i mean
your link
https://www.elecfree.com/circuit/power-supply/lm338k-adjustable-power-supply/
has a 5A transformer and the output is 5A
but my transformer is 4A and i want 5A for 24v dc output
