Copper Clip Junctions Minimize Parasitic Inductance

Building blocks of modern embedded systems, including processors, SoCs, system DRAM, non-volatile memories, sensors, and connectivity modules, have varied power requirements. On one extreme, a system power management IC (PMIC) integrates all or almost all of the required power rails. On the other hand, individual power rails are implemented using discrete dc/dc and LDOs. Thus, the best approach will depend on particular use cases and users’ criteria.

PMICs tend to offer better performance and controllability in a smaller footprint, while discrete solutions are more cost-effective. However, there is a “hybrid” approach to achieve the best of both worlds — using ‘small’ PMICs to implement power rails for performance and programmability, and discretes for everything else.

Here’s a quick video that explains why a hybrid PMIC Approach is beneficial…

ROHM proposes laser diodes that support a wide range of needs in the consumer, industrial, and automotive markets, including high power metal CAN package types that provide high accuracy long range sensing with narrow emission width ideal for robot vacuums and AGVs (Automated Guided Vehicles). Also offered is a new surface mount VCSEL solution that allows for short distance wide range sensing and contributes to the miniaturization of LiDAR/ToF ranging modules by adopting a proprietary structure to achieve a single lobe narrow beam point, making it ideal for facial recognition, industrial robots and driver monitoring systems.


ROHM's optical sensors include high sensitivity, high-reliability phototransistors, infrared light-emitting diodes, transmission type photo interrupters, and reflective type photo interrupters.

In industrial and commercial applications, optical sensors are also being used for distance and temperature sensing and automation in Industry 4.0 applications. For example, optical sensors can detect liquid levels in process engineering facilities, such as petroleum levels in tank farms and hydrocarbon refineries, by integrating an infrared LED, light transistor, and a transparent prism tip.
