Zonal 48 V to 12 V DC-DC converter
Discover our scalable and comprehensive portfolio of zonal 48 V to 12 V DC-DC converters
Innovating to 48 V: Lower cost and reduced wiring harness weight are just some of the potentials of implementing 48 V as the third voltage rail in electric vehicles. Infineon supports you with tailored zonal 48 V to 12 V DC-DC converter solutions based on Si, SiC, and GaN technologies to realize these 48 V-related system cost potentials.
Complete zonal 48 V to 12 V DC-DC topology portfolio
Infineon offers a complete and comprehensive system solution for 48 V to 12 V DC-DC converters, including supply ICs, microcontrollers, gate drivers, and high-power MOSFETs for the multi-phase buck/boost, full-bridge with synchronous rectification and switched tank converter (ZSC) topologies.
Depending on your system requirements, we provide the most appropriate topologies to support bidirectionality, high efficiency, galvanic isolation, as well as size and power density.
48 V to 12 V DC-DC solution integrated into the zone controller
The introduction of automotive zone architecture paves the way for decentralized power supply. At Infineon, we see great potential in integrating the 48 V to 12 V DC-DC into the zone controller unit (ZCU). The advantages are a minimum number of required microcontrollers, no change of architecture, no additional wiring, no single point of failure for the power board network, a significant reduction in the length and complexity of the wiring harness, and also clear separation of the 12 V and 48 V domains.
48 V DC-DC solution for zonal architecture
Application requirements and typical challenges of 48 V to 12 V DC-DCs depend on the integration environment and the zonal architecture concept. Infineon offers a comprehensive system and product portfolio to cover all requirements easily: Microcontrollers to ensure compliance up to ASIL-D, the right topology for an integrated isolation strategy and cooling concept, as well as a suitable loss-of-ground concept.
