Description
General part information
STEVAL-ILL046V1 Series
The STEVAL-ILL046V1 evaluation board is based on the ST1CC40, which is an 850 kHz 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 3 A 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.
The STEVAL-ILL046V1 is provided with 660 mA by connecting a 150 mW sensing resistor to the feedback pin.
