World's First ' Achieves greater miniaturization Built-in SiC MOSFET AC/DC Converters Pioneering and industry-leading SiC technology allowed ROHM to develop new breakthrough products. This includes the world’s first* AC/DC converters that leverage the advantages of SiC, such as higher efficiency and heat resistance, to achieve superior performance in a smaller form factor. This time, in response to numerous customer requests, we developed a compact surface mount package that supports automatic mounting.
