The release of the latest Nano Controller, this is a collaboration between Wiseguy and Poida and was just announced.
New Nano
This is the new controller I'll be using for the Power board.
I will finish off the power board build with a description of the Toriod and the Chokes that I will be using, and more details of the FET mounting hardware.
The following is some of the parts used, I was having trouble finding stock of some items, especially the Buffer transistors, Wiseguy addressed this in his release so I have included that info here.
Cap board screw to PCB7XM4 metal "U" M4 threaded x 4 solder pin standoffs on the main PCB.
Total of 12 needed.
PCB-5 M6 with screws X 4 for Power and Toriod connection.
From www.lcsc.com Minium amount for one board.
Buffer transistors:
MJD45H11-1G X 4
2SD1804L-T-TM3-T X 4
The TO251’s types above are now very hard to find, similarly rated SOT223 surface mount transistors that use the same pin spacing as the TO251s can have the 3 (short) legs inserted into the existing PCB pad holes and soldered.
LCSC has the SOT223 PNP and NPN versions for the buffers which are ~30c ea and have continuous current ratings of ~5A and peak current ratings of ~ 15/20A so the overall cost is low.
HY5608W Power FET X 16 (360A @ 80V 500W rating)
FOD3182V Opto couplers X 4 (none at LCSC but available elsewhere)
2 x B1212S-1W PCB SIP DC/DC 1W modules
1 X B1215-2W
I used a HI-LINK HLK-B1215S-2WR3 but only 8 showing in stock at lcsc.com
LCSC has stock of various brands listed here DC-DC modules
The spacing between the two input and two output pins of the 2W 15v units is slightly different on some, however it's only a matter of drilling two tiny holes for the input pins next to the existing pads, they fit and solder perfectly.
A lot of these components are relatively low cost and it pays to order more than needed.
