AI accelerators pull hundreds of amps at sub-volt rails, and they swing between idle and full load in microseconds. The inductor decides whether your voltage regulator keeps up.
Modern AI platforms concentrate kilowatts behind each accelerator. Multiphase buck regulators — increasingly in TLVR topology — must hold output voltage steady through load steps that would collapse a conventional design. Every phase carries 70 A or more, so winding losses translate directly into thermal problems, and every milliohm of DCR is money spent on cooling.
Co-firing removes the winding-core interface, so losses stay low at sustained training-load currents and the metal-alloy body saturates softly instead of snapping. The monolithic structure also conducts heat out of the winding more effectively — extending thermal margin in 1U and blade densities where airflow is scarce.
