Abstract

DC/DC applications in automotive market are expected to require new system specifications in next years. Because of the spreading of electrical cars, the power line at 48V will be very common. Moreover, the converter chips and external passives are required to occupy less area. A DC/DC solution, meeting such requirements, is presented in this work. The switched capacitors architecture is intended to reduce external passive devices space occupation, whereas sustained electrical power is kept high. This paper discusses a preliminary version of the converter, with experimental results from measurements, and presents the final chip architecture, with some simulation result data.
