The microcontroller can have a regulator, function as a controller and function as a digital isolator with a little air core transformer on the PCB. It won't cost much more than a regulator or controller, packaging dominates at that scale. So basically the extra cost is the micro on the secondary side, big whoop. Also some extra engineering cost, but look at the Murata NXE1 ... compared to the investments for embedding a toroid in the PCB stack I don't think it's all that relevant. Their highest tech module as far as physical design goes has a stone age controller, without any real need for that given component costs. It's a crying shame. |
