48V 12V DC-DC converter
48V /12V DC-DC converter topology benefits
Infineon offers a complete and comprehensive system solution for 48V to 12V DC-DC converters, including supply ICs, microcontrollers, gate drivers and high power MOSFETs.
The requirements for 48V to 12V DC-DC converters vary from application to application, but all require high efficiency, low losses, and high integration for space-saving designs.
Depending on our customer's system requirements, we provide the most appropriate topologies to support as well bidirectionality, high efficiency, galvanic isolation, and size and power density.
We offer expert system knowledge and a complete portfolio for the following topologies: multiphase buck converter, isolated full bridge with synchronous rectification and switched tank converter (ZSC).
The block diagram below shows the basic layout of the semiconductors used for an up to 3 kW DCDC 48V/12V multi-phase buck converter.
