High current power delivery directly to the load

Power hungry applications such as Artificial Intelligence (AI) and Machine Learning (ML) which utilize the latest ASICs or xPUs (TPU/GPU/CPU/NPU/IPU) require vast amounts of current to be delivered to the core at sub 1 V levels, and need to deal with ultra fast load transient demands with the least amount of disturbance to the critical voltages used to feed them.

New power delivery techniques such as Vertical Power Delivery, or VPD are needed, where the power is located directly below the load, which delivers several benefits.

Benefits of using Vertical Power Delivery include:

Huge reduction in board space taken up by alternative lateral power solutions located on the top side
Reduced power distribution network (PDN) losses compared to lateral power delivery solutions
Lower parasitic path from the converter to the load
Improved system efficiency
Ball grid array designed to directly match the pin-map of each xPU/ASIC reducing routing complexity
Customized profile, scalable multi-rail solutions
Modular designs offer ease of manufacturing and vendor flexibility
Increased power delivery efficiency, reduces overall energy consumption

One example of customized VPD solutions is shown above for reference. If this is an area of interest for your next design, please reach out to us to discuss further how we can support your next generation designs.
