Reducing Power Loss with IVR Technology
By supplying power directly to the xPU, our Integrated Voltage Regulator (IVR) lowers power waste, minimizes heat-conversion loss, and optimizes energy delivery.
From Lateral to
Vertical Power Delivery
Today’s voltage regulators employ lateral power delivery, resulting in up to 40% of chip power being wasted to heat.
This is particularly problematic for high-performance computing, where power efficiency is most crucial.
To address energy loss in current power delivery systems, Claros has developed an innovative, vertically stacked Integrated Voltage Regulator (IVR) to revolutionize chip power management.
Our solution integrates power delivery components directly beneath or on the chip, reducing the distance needed to deliver power from inches to millimeters.
By reducing the board’s surface area, our solution allows for greater energy efficiency while reducing power losses by up to 30%.
This transformation holds the potential to significantly boost performance and efficiency of modern electronic devices, paving the way for the more powerful, responsive, and energy-efficient technology of the future.

Why are traditional voltage regulators struggling with modern AI chips?
Modern AI accelerators can draw hundreds of amps and switch power states extremely quickly during operations like matrix multiplication and memory access. Traditional voltage regulators are located on the motherboard, far from the chip, which introduces latency, voltage droop, and power loss due to long electrical paths. Claros’ Integrated Voltage Regulators place voltage regulation closer to, or directly on, the chip, enabling much faster response to power changes, improving power conversion efficiency, and reducing power loss.
How do Integrated Voltage Regulators improve the power efficiency of AI hardware?
AI systems consume enormous amounts of power, often requiring multiple voltage conversion stages between the rack power supply and the processor core. Each stage introduces energy loss. Claros’ Integrated Voltage Regulators reduce these inefficiencies by enabling high-voltage power delivery closer to the processor and converting it locally to the low voltages required by AI cores. This shortens the power path and significantly reduces conversion and distribution losses.
Why are Claros’s Integrated Voltage Regulators important for scaling future AI compute performance?
Next-generation AI processors are pushing toward higher power densities and larger compute clusters, with some chips exceeding 1,000W of power consumption. Claros’s Integrated Voltage Regulators enable more efficient and compact power delivery by supporting fine-grained voltage control across different functional blocks of the chip. This allows AI processors to dynamically optimize power usage, maintain performance during rapid workload changes, and scale efficiently as compute demands continue to grow.
How can Claros’ Integrated Voltage Regulators help increase compute density on AI accelerator boards?
Traditional power delivery on accelerator cards requires large external voltage-regulator modules, along with bulky inductors, capacitors, and power-routing components on the printed circuit board (PCB). These components occupy significant board area, limiting the number of processors or memory devices that can be placed on the card.
Claros’s Integrated Voltage Regulators move much of the voltage regulation closer to or inside the processor package, dramatically reducing the need for large external power components. By freeing up valuable PCB space, designers can allocate more area for additional GPUs, XPUs, or memory devices, increasing the compute density and overall performance of the accelerator card without increasing its physical size.
