The STEVAL-LLL006V1 board is designed to help you 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 - 300 VAC input voltage range into a 60 - 110 VDC 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. A data concentrator unit (DCU) and mobile Android application have been developed to help you explore the functionality of the evaluation board. The DCU consists of a NUCLEO-F401RE development platform, plus the X-NUCLEO-IDS01A4 for sub 1-GHz communication with the LED driver board and a X-NUCLEO-IDB05A1 board for Bluetooth communication with the mobile device.
The mobile application collects lighting nodes represented by the microcontroller and RF module on the evaluation board in a 6LoWPAN mesh network.
Constant current output: 60-110 V / 0.7 A, with ±5% current regulation
High power factor > 0.97 and low THD <15% for entire line and load cycle in quasi resonant mode
Peak overall efficiency (including auxiliary supply) at maximum load > 89%
Digital and remote control section based on STM32 microcontroller
Eireless connectivity with embedded sub-1 GHz transceiver
Five levels of analog dimming
Less than 0.5 W standby power consumption ensures compliance with EnergyStar norms
