ROHM's recently released LogiCoA001-EVK-001 power supply platform is aimed at small to medium industrial and consumer equipment that ranges from 30W to 1kW. The solution takes advantage of both analog and digital technologies to provide the functionality of digital control power supplies while maintaining low power consumption and reduced cost.
Analog-based power supplies are traditionally used for applications such as industrial robots, semiconductor manufacturers and assembly lines that operate in the medium power range. As that equipment has advanced over the years, power supplies have been required to provide increased reliability and precision control. Alternatively, digital-based power supplies offer finer control adjustments and settings but require increased power, making them unsuitable for low and some medium-power applications.
To satisfy both requirements, ROHM developed the LogiCoA001-EVK-001 Buck converter to provide precision control in low and medium-range power applications. The board integrates a 16-bit RISC LogiCoA ML62Q2035 MCU with 2KB of RAM and 32KB of Flash and comes equipped with a 12-bit AD converter and an 8-bit DA converter. The converter also offers I2C and UART for serial communication and a 15-pin I/O port.
ROHM states its LogiCoA001-EVK-001 provides control across various power supply topologies and stores settings such as current and voltage values. It also features an analog-digital fusion control system that combines a digital control block with analog circuitry that includes silicon MOSFETs to provide precision control and increased efficiency.
With that in mind, element 14 has launched a roadtest for those who would like to evaluate ROHM's LogiCoA001-EVK-001 DC-DC Buck converter. Those interested in the road test will receive the converter to use in their current projects or just for evaluation and the out-of-the-box experience. Participants must document their experience via text, images, videos, or other media so that others can follow along and understand what's involved in the project. Enrollment ends on March 4, 2025, so those interested should sign up soon at the link provided above.
