48V Non-Isolated DCDC Converters

As more vehicle systems migrate to a 48V rail, providing clean, stable 12V power for legacy systems and sensitive electronics requires highly efficient, compact, and cost-effective conversion.

Our portfolio of highly integrated, automotive-grade buck regulators and PMICs provides superior EMC performance and high efficiency in a minimal footprint, simplifying design and reducing BOM cost. To enable a seamless and efficient dual-voltage architecture, ensuring all 12V components receive reliable power from the 48V main rail with minimal energy loss and board space.
