Infineon offers a complete and comprehensive system solution for 48 V to 12 V DC-DC converters, including microcontrollers, supply ICs, gate drivers and high-power MOSFETs for the multi-phase bidirectional buck and switched tank converter (ZSC) topologies.
We provide the most appropriate topologies to support bidirectionality, high efficiency as well as size and power density to match your system requirements.
Why integrating 48 V to 12 V DC-DC converter into the zone controller
Integrating a DC/DC to Zone controllers enables faster and more flexible implementation of 48V power distribution by elimination of additional wiring and secondary ECUs while maintaining the current zone architecture. This integration is challenging since zones often have limited cooling and space and are already tasked with a controlling large number of car functions. The combination can be effectively achieved by using the zone controllers existing AURIX™ microcontroller to execute the DC/DC control. Thermal challenges can be addressed by selection of Infineon’s OPTIMOS™ 7 MOSFETs, gate drivers and power supply devices. enabling a DC/DC with the highest possible efficiency and flexibility.
