While the stock market is chasing the fire-fighting power of AI logic chips, a more important story is unfolding in the circuit that powers it. The insatiable power needs of next-generation data centers and electric vehicles (EVs) are forcing a non-negotiable architectural transition from legacy 48-volt systems to 800-volt platforms. This change transforms analog power management integrated circuits (PMICs) from simple components to critical machine components.
Institutional capital is taking notice, quietly building positions on the gatekeepers of this power shift. Two inventors, Texas Instruments NASDAQ: TXN and onsemi NASDAQ: ONplaced at the historic center of this great cycle. Armed with aggressive buybacks, recent sell-side improvements, and structural power to determine the pace of AI expansion, it represents a compelling, and perhaps underappreciated, way to invest in the future of technology.
AI is a Physics Problem, Not Just Code
The AI boom is essentially an energy crisis. As data center racks exceed 100 kilowatts of power density to support advanced GPU clusters, traditional 48V power distribution structures are hitting a thermal wall.
Physics is inexcusable. Since energy loss (as heat) is proportional to the square of current (I²R), doubling the voltage from 400V to 800V cuts the current in half, thus reducing energy loss by 75%. This move is not just a voluntary upgrade; it is an economic and engineering necessity that allows for thin, light copper wires and very little waste heat.
This is where the thesis of analog semis finds its strength: these companies provide the complex chips needed to safely and effectively control high voltage areas.

Texas Instruments has evolved from being a component supplier to a major engineering partner for the biggest names in technology. Collaboration with NVIDIA NASDAQ: NVDA in a complete 800V DC power frame proves that next-generation logic cannot scale without a corresponding jump in power delivery.
By enabling a direct, highly efficient power conversion path from the 800V source to the processor, the technology developed by Texas Instruments significantly reduces the number of points of failure and expensive conversion phases.

onsemi presents a leading position by focusing on smart energy solutions. Aura Semiconductor’s power IP acquisition directly targets the high-end data center market, providing onsemi-critical power management technology at the load point. At the same time, its silicon carbide (SiC) technology has become the gold standard for high-performance EV platforms.
At the 2026 Beijing Auto Show, onsemi’s SiC solutions were installed in approximately 55% of new EV models, including next-generation 900V platforms from global players such as Geely. OTCMKTS: GELYY and NIO NYSE: NIOcementing its role as an important vehicle electrification resource.
Studying the Voltage on Corporate Confidence
An investor can learn a lot by watching how a management team allocates money. In this regard, onsemi sends one of the clearest signs of the market. The board is actively pursuing a massive $6 billion share repurchase program, approved through late 2025, which authorizes it to repurchase nearly a third of its outstanding shares. Investors should see this as more than just financial performance; it is a statement of deep confidence from the leadership that believes that Onsemi’s stock price is undervalued.
To fuel this aggressive repurchase without a distressed investment, onsemi recently announced a $1.3 billion senior convertible note offering. This is a smart move, which provides a quick capital return while protecting the R&D budget for important technologies, such as its Treo platform, which saw an impressive 2.5x sequential growth in Q1 2026. This use of smart valuation reflects the belief that future stock appreciation will far exceed the cost of debt.
Texas Instruments, a more mature and diversified player, shows its strength through operational strength. Executives acknowledged near-term upside in China’s auto sector during their Q1 2026 earnings call, which could be headwinds. However, the financial performance of Texas Instruments shows that this weakness is completely offset by the growth of the Data Center and industrial divisions. The stock’s extremely low short interest of 1.72% suggests that bears have stopped betting against this diversified powerhouse.
Wall Street Reversing Price Index Changes
The sell-side is starting to match this strong thesis. Bank of America recently raised rates for both companies. It raised its onsemi target to $138, citing underappreciated content benefits in AI data centers. It also raised its price target for Texas Instruments to $370, predicting that Texas Instruments’ data center business alone could reach $4.5 billion by 2028, accounting for 18% of total sales.
This pivot is particularly relevant to onsemi. The stock still has a significant short interest of 7.47%, representing over 29 million shares short traded. This creates a compelling technical setup. With management now confirming that the turnaround time for its dying auto business is “well behind us,” the catalysts for performance are aligned. High short floats, large corporate buyouts, and positive volatility in the core business create classic conditions for potential squeezes, where short-covering momentum can drive volatility.
The Analogue Opportunity: A Charged Way Forward
The main argument is simple: for every dollar spent on a high-powered AI chip, a growing share should be allocated to the complex analog technology required to power it efficiently and reliably. The global shift in AI and automotive electrification is a structural, long-term trend that appears poised to benefit both Texas Instruments and Onsemi for years to come.
Of course, no investment is without risk. The semiconductor industry has historically been cyclical, and both businesses face intense competition and are subject to geopolitical risks related to global supply chains. A broader economic downturn could also reduce demand in their key industrial and automotive markets.
Given the strong year-to-date performance, with Texas Instruments’ stock price up 80%, and onsemi up 130%, some investors may prefer to wait for a broader market pullback before starting a position. Cautious investors may consider adding both Texas Instruments and Onsemi to the watch list to monitor attractive entry points, as the 800V main cycle appears to be in its infancy.
