It describes solutions for different concept, hardware and software challenges, starting with selection of proper circuit topology, selection of power switches (switching frequency, voltage class and current ratings), calculation of power budget (efficiency) and thermal analysis, Furthermore, it explains PCB layout electrical/thermal co-simulations, elaborating approach in development of average current control algorithm with the target to enable phase shedding and equal current sharing among active phases, improve the light load efficiency and thermal behaviour. Finally, it tackles the topic of automated code generation and implementation on dedicated microcontroller.enMultiphase 48 V/12 V DC/DC ConverterElectrical/Thermal Co-SimulationAverage Current Control AlgorithmAutomated Code Generation10.18420/in2017_471617-5468
