Alpha and Omega Semiconductor — AI supply-chain exposure

Alpha and Omega Semiconductor designs power semiconductors — MOSFETs, IGBTs and power ICs — the unglamorous components that convert and deliver electricity cleanly to the chips that do the computing. Its parts sit in graphics cards and, increasingly, in the power stages of AI servers, where every accelerator needs a dense, efficient chain to step voltage down and feed it stable current at high draw.

Its hook is exposure to the power-delivery problem that scales directly with AI compute: as accelerators pull more power, the surrounding regulation and conversion silicon becomes a real design constraint, not an afterthought. The model places it as a supplier rather than a central node — it is one of several vendors of a commoditising component — but rising server power density is a genuine tailwind for the category it serves.
