EV growth and the auxiliary power problem

Traction inverter headlines hide the quieter demand spike: 12 V / 48 V auxiliary conversion, onboard charger PFC, and pack-supervision rails. These blocks need PMICs that survive load dump and SiC devices that stay efficient at partial load, not only at peak nameplate power.

Shorter lead times matter here because vehicle programs often pull-in sample and pilot quantities after a late architecture change. Chip Volta keeps a qualified short-lead lane that still runs the released test program — we will not skip outgoing electrical test to make a date.
