As data centers consume more energy to support growing digital demands, engineers at the University of California San Diego have introduced a new chip design that could make powering graphics processing units (GPUs) more efficient. The innovation focuses on a key function in electronics: converting high voltages into the lower levels required by computing hardware. In laboratory testing, a prototype chip successfully performed this type of voltage conversion with high efficiency under conditions similar to those found in modern data centers. The findings, published in Nature Communications , suggest the potential for smaller and more energy-efficient systems in advanced computing environments. Rethinking DC-DC Converters for Modern Electronics At the center of the new design is an improved version of a widely used component known as a DC-DC step-down converter. These converters are found in nearly all electronic devices and serve as a critical link between power sources and sensitive circuits.…
