Texas Instruments outlines a phased, multi-stage transition toward 800V data-center architectures, forecasting TAM growth as designs move from AC-to-DC to 800V and beyond. The company highlights its broad portfolio across Analog, Embedded, and signal-chain components as key to capturing expanding opportunities in current and future data-center power builds.

What did management say about Future data center architectures and 800V TAM?
Management explicitly expects that future data center architectures around “800 volts” will be phased into the market over time. In particular, they described an early progression where systems may start with AC-to-DC, then evolve to AC-to-800V, and then further conversion steps such as 800-to-48V, and 48-to-12V. 1
They also described a longer-term end-state where—once the “SST” is established—data center input will be at DC 800V, with potential for direct conversion from 800V to 12V (or 6V) later. 1
Management’s core argument is that the 800V architecture increases total “TAM opportunity” because it creates more conversion stages and therefore more component “participation points” throughout the power system.
They stated that this “means higher growth of the TAM” because the architecture drives more conversion stages, which benefits TI’s Analog and Embedded side—including different Analog parts involved in every conversion stage, along with embedded controllers and the signal chain. 1
They positioned the 800V transition as:
They also emphasized that this is an area where “the TAM continues to show strength” and that higher voltage generally corresponds to “more opportunity.” 1
Management did not present 800V TAM as a standalone “single product” story; rather, they tied it to how TI’s portfolio spans multiple layers of the power tree and related systems.
Separately from the 800V architecture description, they said many TI chips are used in the power tree involved in the data center, and that additional chips sit on the signal chain side; thus, as data-center power build-out increases (and the number of systems grows), TI expects to benefit from the amount of chips in those systems. 2
They also pointed to being in an “excellent position” from a portfolio standpoint to grow within data center opportunities, including on the ASSP side, with the expectation to grow faster than the overall market. 2
Management’s message is that 800V is not just an incremental voltage change—it is expected to increase the number of power conversion stages during the transition, which in turn expands TI’s TAM by adding more places where TI’s Analog, Embedded controllers, and signal-chain components participate. 1 They also expect the longer-term architecture (after SST is established) to involve 800V DC inputs, with later potential for more direct conversion approaches, while still viewing higher voltage as creating more opportunity. 1
Concretely, management characterizes 800V TAM growth as coming from:

Texas Instruments' Q2 earnings discussion emphasizes that industrial strength arises from broad secular growth and rising content per unit, rather than meaningful price increases. First-half pricing remained flat, and near-term gains stem from volume and inventory dynamics as customers move to newer system generations, suggesting a volume-driven recovery with pricing potentially contributing later.
