Figure 1: PRM™ and VTM™ are the building blocks of FPA. PRMs are selected based on the system input voltage range and power requirements; VTMs are selected based on the output voltage range and current requirements. The PRM can be mounted anywhere in the system where convenient; the VTM should be mounted as close to the processor core as possible

The recent introduction of new clustered AI ASIC processor based supercomputers are pushing the boundaries of power delivery networks to levels that were never imagined just a few years ago. With current levels approaching 100 kiloamps/ASIC cluster, innovation is needed across power system architectures, topologies, con

Figure 1: An example of a standard dc-dc converter application

If your DC-DC converter doesn’t work, you might check all the obvious causes that it could stem from - such as it not being plugged in correctly, not turned on, the input fuse having blown, etc. - none of which appear to be the issue.  So you are completely perplexed as to why it won’t play ball. But, ha
