说明

  • 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 3A 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 m-Ohm sensing resistor to the feedback pin. The overall application size is minimized, thanks to the high switching frequency and ceramic output capacitor compatibility

主要特色

  • Input Voltage
    3 to 18 V
  • Output Current
