STEVAL-POEL45W1 Data brief Power over Ethernet (PoE) powered 45 W LED driver with Bluetooth Low Energy (BLE) enabled control reference design Features PoE-PD IEEE 802.3af/at/bt compliant Constant current output, working in buck topology Output current 1.4 A with < 0.05% current regulation Number of LEDs connected at output: 6 11 white LEDs (3.3 V each) Wireless ON/OFF and dimming control with PoE Lighting Android application Digital dimming with 1% resolution LED driver input voltage range 37 57 V DC Peak efficiency at maximum load > 95% Low standby power consumption < 100 mW Comprehensive set of protections: open/no-load circuit protection short/overload circuit protection RoHS compliant WEEE compliant Description The STEVALPOEL45W1 Power over Ethernet (PoE) powered LED driver reference design delivers a power output of 45 W and dims LEDs down to 1% of the maximum brightness without any flicker. The solution supports remote dimming control via Bluetooth with the PoE Lighting Android application (available on Google Play). Product summary You can use this reference design to develop complete indoor network-powered Power over Ethernet lighting solutions with IP-based Powered Devices (PDs), without additional AC power (PoE) supplied, 45 infrastructure, and extend the functionality to include remote data management via W LED driver with STEVAL- existing LAN networks. Bluetooth Low Energy POEL45W1 The reference design features a highly integrated PM8805 IEEE802.3bt-compliant (BLE) enabled control reference design Powered Device (PD) PoE interface, a high efficiency LED6000 LED driver able to source up to 3 A current, and a certified SPBTLE-1S Bluetooth Low Energy DC Firmware for the STSW- module, compliant with BT specifications v4.2 and BQE qualified. STEVAL-POEL45W1 POEL45FW For new designs, the BLUENRG-M2SA module for Bluetooth low energy v5.2 is IEEE802.3bt PoE-PD interface with integrated PM8805 recommended. dual-active bridge SPBTLE-1S and BLUENRG-M2SA are pin to pin compatible. 3 A, 61 V monolithic The STSW-POEL45FW board firmware is programmed via the STSW- current source with LED6000 BNRG1STLINK utility. dimming capability Very low power application module for SPBTLE-1S Bluetooth Smart v4.2 Very low power application processor BLUENRG- module for Bluetooth M2SA low energy v5.2 Android app for STEVAL-POEL45W1 PoE Lighting LED driver DB3730 - Rev 4 - March 2021 www.st.com For further information contact your local STMicroelectronics sales office.STEVAL-POEL45W1 Schematic diagrams DB3730 - Rev 4 page 2/5 1 Schematic diagrams Figure 1.
