A dummy load. Peak current is 5A. That is currently (hahaha) limited by using only 5V as the reference voltage for the opamp. LTSpice simulations (with a different opamp) showed possible oscillations at a set-current of above 2A. I had to add another BW-limiting capacitor to the opamp that drives the MOSFETs. If I'm lucky the real thing won't need it. If it does I'll have to bodge it. I won't immediately order the V0.2 PCB for that. I only need one working board for personal usage. • BOM • schematic
