Procurement managers across Asia opened revised price lists on July 1 to find increases from nearly twenty suppliers of analog and power semiconductors, the latest in a series of staggered price moves that has defined the sector this year. The notices vary in size, with some companies raising prices on specific product lines and others adjusting entire catalogs, but the direction is uniform. A distributor in Shenzhen who handles power-management chips said he has stopped quoting prices more than a week out because suppliers keep revising them.
The companies raising prices sit in a corner of the chip industry that rarely makes headlines. Analog and power chips regulate voltage, manage batteries, drive motors and convert electricity in everything from phones to factory robots. They are not the headline-grabbing AI accelerators, but every data-center rack depends on dozens of them, and the build-out of AI infrastructure has pulled demand for power chips sharply higher. The sector’s leaders, companies with decades-old franchises in power management and signal conditioning, are among those tightening terms.
Several of the suppliers said their order books are full through the third quarter, and executives describe capacity visibility that was unthinkable two years ago. One manufacturer of power-management integrated circuits told customers in a July 1 notice that it is prioritizing shipments for AI server programs and that standard lead times have stretched beyond twenty weeks. Distributors say they are rationing popular part numbers and asking customers to submit firm forecasts before receiving allocation.
The price increases trace to two forces that have met in the middle of the supply chain. The first is cost: foundries have raised wafer prices, and the raw materials behind packaging, substrates, copper lead frames and epoxy resins have all become more expensive. The second is demand: AI data centers consume power at a scale that requires new generations of voltage regulators, and the power-delivery path inside a GPU server is now one of the most expensive parts of the machine. The two forces reinforce each other, because the foundries raising wafer prices are the same ones running full on AI orders.
Analysts say the combination is giving the analog and power sector pricing power it has not exercised in years. The industry has historically been a slow-moving business, with products that live for a decade and prices that drift downward. The current cycle has inverted that pattern, and suppliers that own their own fabrication or are deeply tied to upstream capacity are capturing the gains first. The sector went through a brutal correction in 2023 and 2024, when distributors burned off inventory and prices fell for six straight quarters; the current upswing is recouping those losses.
The shift is concentrating share among a handful of players. Companies with integrated design-and-manufacturing operations, or with long-term foundry commitments, can guarantee supply to customers who are desperate for it, and those customers are signing multi-year agreements to lock in capacity. Smaller fabless firms, by contrast, are squeezed between rising wafer costs and customers who refuse to absorb the full increase. Analysts expect the gap between the two groups to widen through the end of the year.
Not every end market is strong. Automotive demand has recovered unevenly, and some industrial customers are still working through inventory built during earlier shortages. Suppliers are responding by steering capacity toward AI, data-center and server programs, where pricing is firmest, and away from consumer electronics, where manufacturers are resisting increases. Phone makers have pushed back hardest, and some have already begun switching certain power chips to suppliers with spare capacity, according to people familiar with the matter.
The price rises are not without risk. Extended increases can push customers to redesign products around cheaper components, or to qualify second sources. A smartphone maker that redesigns a power circuit takes eighteen months to bring the new design to market, so the risk for suppliers is delayed rather than immediate, but it is real. Inventory behavior matters too: customers who fear further increases may double-order, building the kind of phantom demand that preceded the 2023 correction.
For now, though, the arithmetic favors the suppliers. Every major cloud company is adding data-center capacity, and the power-delivery content per server is growing faster than the number of servers itself. One analyst who covers the sector called the current quarter a seller’s market, noting that the companies announcing July increases are the same ones that raised prices in April and are likely to do so again in the fall.
The quieter winners may be the foundries. As analog suppliers pass on wafer costs, the manufacturers of those wafers are running full, and their pricing power feeds directly into the next round of increases. The cycle, executives say, has a self-reinforcing quality that no one in the supply chain is eager to break.
