The BD7682FJ-LB allows the easy implementation of SiC-MOSFETs to an AC/DC converter AC/DC converter design. Compared to silicon MOSFETs used in conventional AC/DC converters, SiC MOSFETs enable AC/DC converters with improved power efficiency by up to 6%.
Components used for heat dissipation are not required (50W Class power supplies), leading to greater compactness. The specification of BD7682FJ-LB also include multiple protection functions that enable support for high voltages up to 690VAC, making them ideal for general industrial equipment while improving reliability.
Rohm uses market-proven analogy technology with SiC power semiconductor expertise to develop the industry's first AC/DC converter controller specialized for driving SiC MOSFETs. Various protection circuits enable high voltage operation in AC/DC converters up to 690VAC.
In addition to overvoltage protection for the supply voltage pin and brown in/out (undervoltage) countermeasure for the input voltage pin, overcurrent and secondary overvoltage protection functions are included, enabling continuous operation in industrial equipment while improving reliability considerably.
