power supply miniature help

6 posts / 0 new

good, i want to make a 220vac to 5vdc power supply.
5VDC with a current of 0.5 A.

The font I want is as small as the font in the image.

I was thinking of using the abs10 rectifier bridge, and the integrated lm364dn. but still missing more components to make the font.

thank you for help on how to do

Hi pedroborges,

For your 220VAC to 5VDC power supply with compact size, you might want to consider using LinkSwitch product family of Power Integrations.

We have a reference design for 85 VAC - 265VAC input, 5V / 0.5A output, non-isolated supply using LNK623D that is very compact (1 x 1 inch PCB size) in the link below



thank you very much,
tell me one thing now, can you get me a compact 1 amp 5v power scheme ?

Hi pedroborges,

We also have a reference design for a compact 5V 2A output power supply:

thanks, the link sent from the 5 volt 500 ma I found a folder named der-831_gerber.

there is the eagle file from pcb but error opening

Hi pedroborges,
The .brd file in the folder is a PCB layout file, but it was created using a different software - Allegro PCB Designer (not Eagle).
If you want to view only the layout gerber files, you may download "Allegro/OrCAD FREE Physical Viewer" from Cadence website:
If you want to edit the Schematic and PCB file, you would need to have Cadence OrCAD software. Download website is in the link below:
