DCC-1848 Prototype

Saturday, November 24, 2007 10:08:04 PM (Central Standard Time, UTC-06:00) ( )

While waiting for the IO-module PCB to arrive, I'm starting to design the PCB for my new PSU.

It's a DC-to-DC converter, that will allow powering of the SC-1, or for that matter, any project requiring +/-18 and +48VDC from a 12VDC or 12VAC source.

So my goal is to be able to power the SC-1 using wallwarts or batteries in the future.

The battery option will be useful for tapers and other field recordists.

Here's the preliminary PCB component layout.

The PCB measures 2" x 3.25" only.

Done... just need to do some component size checking, and then I'll send it out for prototype manufacturing.

To fit in a 1u rack, the heatsink must be 1" high.

I don't know if this thing will work, I have not breadboarded this... so I'm doing straight into a PCB. With switching PSU being sensitive to PCB layout, I'm not 100% sure if I did everything right.

I'll need to re-read the datasheets and look for PCB design guidelines and fix anything that needs fixing before sending this off.

Fixed size of capacitors.

New PCB size... 2" x 3.375"
