Manufacturing and Engineering Priorities
Minimize gate-drive and high-current commutation loops.
Use Kelvin sensing for shunts and keep analog measurement away from switch nodes.
Size copper using continuous current, peak current, allowable temperature rise and cooling conditions.
Coordinate heat sinks, thermal pads and mounting pressure with the mechanical design.
