The BD9G341AEFJ utilizes ROHM's high voltage 0.6um BiCDMOS process to achieve an industry-leading maximum breakdown voltage of 80V (the highest in ROHM's non-isolated DC/DC converter lineup) and a continuous operating input range of 12 to 76V, while market-proven advanced analog design technology results in the highest conversion efficiency in its class.
In addition, multiple protection circuits minimize heat generation, even during output pin shorts (contact), preventing possible damage and increasing reliability vs. conventional products. And the compact 8pin package requires fewer parts and reduces mounting area, contributing to easier PCB placement and end-product miniaturization.
Features:
－ Class-leading 76V breakdown voltage
－ The industry's highest efficiency
－ Output pin protection prevents damage for improved reliability
－ Compact package reduces mounting area and requires fewer external parts
