ROHM Begins Mass Production of its BD9P Series Automotive DC/DC Converters
Published2020.10.27 16:34Contributes to low power consumption through high power conversion efficiency
ROHM announced on the 26th that it has developed a total of 12 models of the "BD9P Series" primary DC/DC converter for automotive use.
The "BD9P Series" employs proprietary, cutting-edge power technology, "Nano Pulse Control™," and a new control method to achieve both high-speed response and high efficiency. The power IC achieves 92% power conversion efficiency under high loads and 85% under light loads.
Additionally, it operates stably when the input voltage from the battery fluctuates, and output overshoot is suppressed to less than 1/10 of its original value when the voltage fluctuates. This eliminates the need for the additional output capacitor required for conventional overshoot countermeasures.
This new product combines with the secondary DC/DC converter "BD9S Series" connected at the rear end to create a high-efficiency, high-speed power supply circuit. This product combination, along with ROHM's proposed reference design "ROHM Solution Simulator," can reduce development costs at each design stage.

"Design of high-functioning small-sized battlefield equipment, using SBC as a solution"
Modern vehicles are equipped with numerous electronic components that perform a variety of functions. Automotive application manufacturers must design their products to operate properly within the limited power and space constraints of a vehicle without causing interference to or being affected by other products. System-based chips (SBC) integrate individual ICs that handle power supply, communication, and management functions into a single IC, which enables reduction of PCB size through their utilization.

A single misaligned light means 'defect'… Vehicle interior lighting now guarded by semiconductors and software
Automotive interior lighting is moving beyond its role as 'auxiliary lighting.' As it becomes a core element of user experience (UX) that expresses brand identity through color and animation while reflecting driver preferences, the LED interior ambient lighting market is growing rapidly. In connection with this, we met in advance with Choi Young-jae, Research Director at Dabo Corporation, who will present a technical webinar session on "Intelligent LED Interior Lighting Solutions Illuminating Future Vehicles," to hear about market trends and changes in design requirements.
