ROHM Offers LogiCoA™: the Industry's First Analog-Digital Fusion Control Power Supply Solution

ROHM has established LogiCoA™, a power supply solution for small to medium power industrial and consumer equipment (30W to 1kW class). It provides the same functionality as fully digital control power supplies at low power consumption and cost equivalent to analog power types.

Analog controlled power supplies are commonly used in industrial robotics and semiconductor manufacturing equipment that operate in the medium power range. However, in recent years these power supplies are also required to provide a high level of reliability and precise control that make it difficult to meet market demands with analog-only configurations. On the other hand, while fully digitally controlled power supplies enable fine control and settings, they are not widely adopted in the small to medium power range due to the high power consumption and cost of the digital controller. To address this issue, ROHM developed the LogiCoA™ power solution that leverages the strengths of both analog and digital technologies. High performance low power LogiCoA™ MCUs are utilized to facilitate control of a variety of power supply topologies.

The LogiCoA™ brand embodies a design philosophy of fusing digital elements to maximize the performance of analog circuits. ROHM’s LogiCoA™ power solution is the industry’s first “analog-digital fusion control” power supply that combines a digital control block centered around the LogiCoA™ MCU with analog circuitry comprised of silicon MOSFETs and other power devices (more info).
