ROHM has launched LogiCoA, a cutting-edge power supply solution designed for small to medium-power industrial and consumer equipment (30 W to 1 kW). This solution combines the functionality of fully digital control power supplies with the low power consumption and cost efficiency of analog power types.
LogiCoA leverages high-performance, low-power MCUs to manage various power supply topologies, fusing digital elements to enhance analog circuit performance. This hybrid approach addresses the limitations of analog-only configurations and the high power consumption and cost of fully digital systems.
