HB LED driver with inhibit based on the ST1CC40 in an SO-8 BW package
  • active 活性

The STEVAL-ILL046V2 demonstration 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 = 100mV/ILED

The STEVAL-ILL046V2 is provided with 660 mA by connecting a 150 mΩ sensing resistor to the feedback pin.

The overall application size is minimized, thanks to the high switching frequency and ceramic output capacitor compatibility.

The STEVAL-ILL046V2 demonstration board is fully protected against overheating, overcurrent and output short-circuit.

The inhibit mode minimizes the current consumption in standby (6 μA) to maximize battery life in portable devices.
