ROHM's Ultra-High-Efficiency 76V DC/DC Buck Converter
Provides high reliability and greater energy savings ideal for communications infrastructure and industrial equipment
KYOTO and SANTA CLARA, Calif., Oct. 27, 2015 /PRNewswire/ -- 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.
In response to the increasing need in a number of sectors to conserve energy while providing high breakdown voltages to prevent damage due to instantaneous voltage surges and transients, ROHM leveraged its advanced, cutting-edge power processes and vertically-integrated production system to develop products for the industrial equipment market that demands long-term, stable supply along with high reliability to ensure continuous operation.
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.
Key Features
1. Class-leading 76V breakdown voltage
Cutting-edge 0.6um high voltage BiCDMOS processes are utilized to develop a non-isolated DC/DC buck converter with an integrated MOSFET featuring the industry's highest maximum breakdown voltage in its class. As a result, support for input voltages up to 80V (max.) and 76V (operation) is provided, ensuring sufficient margin against sudden surge voltages in applications that normally operate at 48V and higher, improving system reliability.
2. The industry's highest efficiency
The industry's highest power conversion efficiency in the 76V DC/DC converter class has been achieved by leveraging advanced market-proven analog design technology. Efficiency is increased by 1.5% compared to conventional products during stable operation and by as much as 19% (300kHz oscillation frequency, 48V supply/5V output), improving energy savings in industrial equipment.
3. Output pin protection prevents damage for improved reliability
Unlike conventional protection functions that normally cannot suppress heat generation during output shorts (contact), ROHM's proprietary protection function minimizes heat generation during accidental output shorts, preventing damage and improving system reliability.
4. Compact package reduces mounting area and requires fewer external parts
The BD9G341AEFJ is offered in a compact 8pin package (4.9mm x 6.0mm, t=1.0mm) and features a highly integrated design that reduces the number of parts required from 17 to 12, simplifying end-product design, BoM costs, and development efforts.
Applications
-- Communication infrastructure such as switching and base stations, office
telephone systems, routers, and other equipment requiring 48V input.
-- Motor devices exposed to high surge voltages (e.g. electric bicycles,
vacuum cleaners, industrial controllers).

Pricing: $1.82 /unit (2500pcs)
