On April 13, 2026, it was reported that as artificial intelligence and high-performance computing continue to advance, the energy consumption problem in data centers has become an increasingly pressing concern. A research team of engineers from the University of California, San Diego, has put forward a cutting-edge chip power supply design and successfully developed a prototype chip capable of achieving highly efficient voltage step-down conversion. This innovative chip combines piezoelectric resonators with capacitors. Through this unique combination, it can effectively reduce a 48-volt input voltage to 4.8 volts. Notably, it attains a peak efficiency of 96.2% and is able to deliver an output current that is four times greater than that of traditional piezoelectric designs. This significant breakthrough is anticipated to significantly boost the power conversion efficiency of graphics processors. Moreover, it is expected to spur the development of more compact and energy-efficient computing systems. The relevant research findings have been published in the esteemed journal Nature Communications.
