STMicroelectronics STEVAL-POEL45W1 Evaluation Board
STMicroelectronics STEVAL-POEL45W1 Evaluation Board is a PoE-enabled constant current LED driver with BLE control. The board features a PM8805 PoE interface, LED6000 LED driver and BLUETOOTH® module SPBTLE-1S. The PM8805 embeds a double active bridge, a hot swap MOSFET, and an IEEE802.3bt-compliant PoE interface. The LED6000 is a step-down monolithic switching regulator designed to source up to 3ADC current for high power LED driving. The 250mV typical RSENSE voltage drop enhances the efficiency. Digital dimming is implemented by driving the dedicated DIM pin. The SPBTLE-1S is a BLUETOOTH low Energy System-on-Chip application processor certified module. It is compliant with BT specifications v4.2 and BQE qualified.
