Analog Devices completes US$1.5bn acquisition of Empower Semi.

ADI closes its purchase of the integrated voltage-regulator maker — power delivery for AI compute becoming strategic silicon.

Jul 2026SemiconductorsSolomon Partners Briefing

Analog Devices has completed its US$1.5bn acquisition of Empower Semiconductor, a maker of integrated voltage regulators (IVRs) that place power conversion directly alongside — or inside — the processor package.

The strategic logic is the power wall. AI accelerators now draw kilowatt-class power at sub-volt levels, and delivering that current efficiently across a board is a first-order engineering constraint. Integrated regulation shortens the delivery path, cutting losses and freeing board area.

For ADI, the deal slots a high-growth, AI-levered product line into its power franchise — and takes a strategic component off the table for rivals in the data-center power chain.

Our read.

Power delivery has quietly become one of the best-positioned niches in AI infrastructure — every watt saved between the rack and the die is margin. Expect continued M&A across the data-center power chain, from IVRs out to the grid interconnect.
