Hi all,
It still seems to be the rage to make up through hole power stages still, so I thought I'd have a go at it myself. All the cool kids are doing it. Right?
Started it at 5pm this afternoon and got this far just before dinner at 8:30, so not much time invested so far.
If anyone is interested, I'll complete it and push it to github. Just thinking I'll add a PICOFLEX ribbon connector to get all the connector gubbins. Might also add some footprints for snubbers.
With a decent FET choice, you could easily have 200A continuous, 400 or so peak I reckon.
100x 50mm, so pretty damned tiny. Need to add more electrolytic caps though! A row of 16mm OD caps would only increase the total size to 60mm or so, so still not huge!
Layout as below, scheme for routing and returning gate signals very neatly
Connector in, all drivers, control, opamps on another board.
