ICs
Strengthening our automotive business while also expanding overseas markets and our industrial equipment business to become a major global player
In the IC business, we develop products with a focus on analog ICs such as power supplies, motors, analog front ends, and amplifiers. In particular, we are focusing on Application Specific Standard Products (ASSP) in which our Product Marketing Engineers (PMEs) accurately identify our customers’ development trends so that we can proactively develop products that fulfill our customers’ needs. In addition to engaging in close communication with the customers, the PMEs value customer feedback, which can be applied to product development, and are characterized by meticulous attention to detail ranging from support during the product launch to follow-up at the time of mass production.
Naturally, in addition to product development, we also recognize the reduction of GHG emissions as a priority social issue. Because motors and power supplies account for the majority of power consumption around the world, ROHM's ICs enable a reduction in power consumption by motors and power supplies. With the advance of electrification and automation in every field and the growing need for device energy saving and miniaturization, we hope to help solve environmental issues by expanding our lineup of high val-ue-added IC products to meet such needs.
Moreover, one of our future tasks is to develop not only the domestic but also overseas markets, and we are focusing our efforts on industrial equipment in addition to automobiles.

Toward the Realization of a Sustainable Society
Development of isolated DC-DC converters which aid in miniaturization and the reduction of the number of man-hours spent on reducing noise in the design process for EV applications
EVs are equipped with applications such as traction inverters which drive the motors, electric compressors for the air condi-tioner, and PTC heaters which increase the temperature of the vehicle interior. Since these components are driven at high voltages, the primary side circuit with the battery must be isolated from the secondary side circuit with the motor, to ensure safety. Meanwhile, the noise suppression man-hours for different switch frequencies were an issue in previous isolated circuit configurations due to the size of the mounting area and power consumption as well as the output current. ROHM developed an isolated flyback*1 DC-DC converter which is optimal for power supplies for driving the gate drivers installed in these appli-cations. Our new products contribute to application miniaturization and reduced noise design man-hours by realizing a circuit configuration which does not require a photocoupler*2 and stable switching frequency characteristics.
- *1 Flyback: a type of circuit which is used in the configuration of an isolated power supply. It is suitable for applications up to 100W and is superior in terms of the number of components and cost.
- *2 Photocoupler: an electronic component which converts an electrical signal input into light with light-emitting elements and then converts it back into an electrical signal with light-receiving elements.
