6v to 24v conversion

Lots of ways. What is the current requirement?

7805 24v to 5v ckt

A very simple way would be using a 7805 regulator. It just works and yoy don't have to think.

But if you plan to output any more than some fifty milliamps then you should consider mounting it on a heatsink.

Or pepakpan should think about DC-DC converters like mc34063.

-40v to 5 v conversion

Hi buddy,
The current requirment on the output at 5V decides the method of converting 24 to 5V.

Agreed. Thats the sensible way. But it depends of how much current, and also the power supply (if it is a battery/solar cell or iv it's just a power outlet with a DC supply)

Now we waiting this thread will be put as solved by pepakpan.

power supply 24v to 5v

I would like to thank all for their replies. I tested with 7805 and its working.

Added after 4 minutes:

My one more question is...

I would like to design a pcb with atmega8 controller. So to program this controller I need to have some interface between controller and computer. One more thing is i will program this pcb only once. So there any way of programming it without having USB or RS232 connectors on pcb.

If it is a DIP package, you may use AVR programmer from www.ikalogic.com/isp.php/
you may implement it on a bread board and after programming, you may transfer your ATMEGA8 to the user board.

24v to 5v circuit

if u use the 7805 regulator to convert 24 to 5 volt then u will lose lot of energy as heat and power dissipation of 7805 will increase as well , decreasing the power dissipation of lm7805

better use Dc-Dc converter , if u are to keep the efficiency high

drop 24v to 5v

afterall, you can use 6V and derive 5V for the few mA load using a Low Drop Out( LDO) regulator like LM2931-5 or LM1117-5
upto say 50mA even an input of 5.6V is sufficient got get 5V

As such no point in using 25V input.

8 volt 5 volt conversion

the power supply 24V is not my wish... its a standard power supply used in a system where i have to use this pcb....so its the only option...
