Rohm offers novel power supply solution
Rohm has launched a power supply solution, called LogiCoA, for small to medium power industrial and consumer equipment (30W to 1kW class).
The company says LogiCoA provides the same functionality as fully digital control power supplies at low power consumption and cost equivalent to analogue power types. It combines a digital control block centred around the LogiCoA MCU with analogue circuitry comprised of silicon MOSFETs and other power devices.
By combining the advantages of analogue circuitry with those of digital control, it is possible to maximise the potential of circuit topologies, according to Rohm. The design concept can be applied not only to the power supply field, but also to power solutions as a whole.
An evaluation reference design REF66009 now allows users to experience the LogiCoA power supply solution in a non-isolated buck converter circuit. Various tools necessary for evaluation are also offered, including circuit diagrams, PCB layouts, parts lists, sample software, and support documents, while actual device evaluation is possible using the optional LogiCoA001-EVK-001 evaluation board.
