What is it?

A 12V to 5.0V DC/DC step down converter based on the Texas Instruments LM2743 IC.

Why did you make it?

To efficiently convert 12 VDC to 5 VDC. To power a load of hard disk drives on an ATX PSU that can carry loads of current on the 12V rail and a lot less on the 5V rail.

What makes it special?

Maximum design load: at least 8 Amps
PCB made in Germany (by Würth); price was EUR 41,43 per PCB
PCB designed and assembled in The Netherlands (by Bekking Electronics Design)
without inductor (I can supply Coilcraft 1419D/1420D/1436D or WE 744364100 1423)
without Cin (X5R, 22uF, 10%, 25V, 2mOhm ESR)
without Q1,Q2 MOSFET (TI CSD16321Q5)
88 x 35 mm small dimensions
4 Oz (70 µm) copper
4 layer PCB
