Regulated PSU PCB

D_GR8_1 · 30th November 2004, 06:55 AM

I am designing a PCB based on carlosfm's thread in regards to Regulated PSUs.

The attached screenshot is of half the board. The other half will be a mirror image. The intention here is to get feedback on my current design and how I can improve it before I go and do the other half.

This design is for DIY only, and I will not be making it commercially avalable, so now that we got that out of the way, please fellas, post your comments.

Thanks!

what about the U1?I recommend that you should leave some rooms for set up U1's heatsink.

The actual heatsink will be U-shaped with the fins extending to the front of the regulator.

The only reason I put them so close together is because carlosfm suggested that C3 should be as close to the regulator as physically possible.

here is the finished product:

And this is what it might look like:

In my opinion the left side of the board can be made simpler (and this will make the board small) if the following idea is used.

I see your point, however the way you see it there, it is because of the actual PCB connector that I will be using for the incoming AC from the toroid.

Here is the part:

Hi D_GR8_1

They are available in Jaycar and are about AUS$3-4.

I am actually getting all my supplies from a Jaycar supplier, a company called Electus, where everything is half-price!

no offence . but digi's are smaller and would work better small mans smaler chassis. and on the other note you can use peter daniel's SUPERB chassis. : O )
