STMicroelectronics STEVAL-ILL046V2 Evaluation Board
STMicroelectronics STEVAL-ILL046V2 Evaluation Board is based on the ST1CC40, which is an 850kHz fixed switching frequency monolithic step-down DC-DC converter designed to operate as a precise constant current source with an adjustable current capability of up to 3A DC. In closed-loop operation, the ST1CC40 feedback pin voltage is 100 mV. Thus, the sensing resistor calculation is expressed as Rs = 100 mV/ILED. STMicroelectronics STEVAL-ILL046V2 is provided with 660mA by connecting a 150mW sensing resistor to the feedback pin. This evaluation board is fully protected against overheating, overcurrent, and output short-circuit.
