1 / 4 page May 2016 DocID024104 Rev 2 1/4 For further information contact your local STMicroelectronics sales office www.st.com STEVAL-ILL046V1 HB LED driver with inhibit based on the ST1CC40 in a QFN package Data brief Features 3 to 18 V operating input voltage range 850 kHz fixed switching frequency 100 mV (typ) current sense voltage drop 6 µA standby current in inhibit mode ±7% output current accuracy Synchronous rectification Embedded compensation network Internal current limiting Ceramic output capacitor compliant Thermal shutdown RoHS compliant Description 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. The overall application size is minimized, thanks to the high switching frequency and ceramic output capacitor compatibility. The STEVAL-ILL046V1 evaluation 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. |
