12v dc to 5v dc converter

[RB]

Hi, new guy here so please allow for my lack of knowledge.

Installed a XM radio in my truck. Uses a 12v to 5v converter in a
power port. Would like to wire to the fuse block but need to build a
converter.

What I need is a 12v dc to 5v dc, (6v dc 1mA maximum )

Here's the rub, good with my hands but not skilled enough to design
the converter.

If someone could help with a simple schematic or line drawing with a
parts list I think I can build it.

Again, excuse my lack of skills, just looking for a bit of help.

Thanks

RB

1 mA?

1 mA?

Got the 1 mA from here. About 3/4 down the page under technical
specifications.

Does seem a low on power.

Get an LM309K from the radio shack.

4 or 5 AA batteries might do a couple thousand hours at 6 Vdc, 1 mA.

This is just a suggestion as to a what may be a simple solution for you:

Wire from the fuse box to a chassis-mounted cigar/accessory socket. The
latter mounted somewhere accessible but not likely to get too
hot/wet/etc. You say a truck - so I would imagine that there are plenty
of out-of sight suitable places for this.

To all, thanks for the responses.

Sue, your idea to install an additional socket might be just the
ticket. Right now the unit is plugged into the extra outlet on the
rear of the console. The power adapter sticks out a ways from this
socket. I can tuck an additonal socket inside the forward console,
and all wires will be out of sight.

The thought of building my own power supply did not take cost as a
factor. Just thinking of a way to get the job done.

Again thanks for the help.
