STEVAL-LLL006V1, EVAL BOARD, SMART LED DRIVER
Smart LED driver using 6LoWPAN mesh network for outdoor street lighting. It is designed to help users to evaluate high power LED lighting solutions with comprehensive power management and wireless connectivity. The board integrates an intelligent power conversion stage thanks to the HVLED001A LED lighting controller with various operating modes, sensing and protection mechanisms and highly efficient switching based on the STP21N90K5 power MOSFET. The board is able to convert a wide 90 to 300VAC input voltage range into a 60 to 110VDC output in constant current mode with high power factor and low THD. The on-board STM32L071KZ microcontroller is able to receive remote on, off and dimming commands via the embedded SPSGRFC sub-1 GHz transceiver module.
