“Incorporating a SiC mosfet and control circuitry optimised for auxiliary power supplies for industrial equipment in a single package significantly reduces the number of parts required when compared to the conventional designs. It also aids minimising both the component failure risk and the amount of resources required to develop systems using SiC mosfets,” according to the firm.
The part is the BM2SCQ12xT-LBZ, and is expected to find use in servos and inverters in robots and PLCs (programmable logic controllers), and in street lamps.
Protection against over-load, Vcc over-voltage, secondary over-voltage and over-current is included, as is thermal shut-down.
“Quasi-resonant method is adopted for the control circuit that enables operation at higher efficiency and lower noise than conventional PWM systems, minimising the effects of noise in industrial equipment,” said Rohm.
It comes in a TO-220 6M package and is in production, with evaluation boards expected later this year.
