Abstract:This work presents a self-timed resonant highvoltage (HV) dc-dc converter in HV CMOS silicon-on-insulator (SOI) with a one-step conversion from 100-325 V input down to a 3.3-10 V output, optimized for applications below 500 mW, such as IoT, smart home, and e-mobility. Unlike bulky power modules, the HV converter is fully integrated, including an on-chip power stage, with only one external inductor (10 µH) and capacitor (470 nF). It reaches a high power density of 752 mW/cm 3 , an overall peak efficiency as hig… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
