Ultra-High Efficiency 76V DCDC Buck Converter

ROHM is announcing the availability of a 12 to 76V input, 3A variable output voltage, DC/DC Buck converter with integrated 76V MOSFET optimized for high power (high voltage x large current) applications such as motors, factory automation equipment, communications infrastructure, and industrial machinery.

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 advancedanalog 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.
