> I guess every μΩ of resistance counts More importantly, every μH of inductance counts. Running 200 A into the chip is not that difficult, the real difficulty is the high di/dt - how to maintain a nice regulated voltage when the current consumption suddenly raises from 10 A to 200 A within a few microseconds.
