ROHM Semiconductor's DC/DC converter with built-in MOSFET achieves one of the highest step-down ratios in the industry (at 2 MHz) required for 48 V automotive systems such as mild hybrid vehicles.

The BD9V100MUF-C integrates ultra-high-speed pulse control technology (nano pulse control) created by combining proprietary circuit design and layout with original processes, enabling low voltage 2.5 V output from 60 V (maximum) input at 2 MHz (resulting in a high step-down ratio of 24:1). This makes it possible to miniaturize peripheral components while at the same time configure voltage conversion from high to low voltages using a single IC whereas 2 or more ICs are conventionally required, contributing to greater miniaturization and simpler system design.
