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 VDC

• 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

DescriptionThe STEVAL–POEL45W1 Power over Ethernet (PoE) powered LED driver referencedesign delivers a power output of 45 W and dims LEDs down to 1% of the maximumbrightness without any flicker. The solution supports remote dimming control viaBluetooth with the PoE_Lighting Android application (available on Google Play).

You can use this reference design to develop complete indoor network-poweredlighting solutions with IP-based Powered Devices (PDs), without additional AC powerinfrastructure, and extend the functionality to include remote data management viaexisting LAN networks.

The reference design features a highly integrated PM8805 IEEE802.3bt-compliantPowered Device (PD) PoE interface, a high efficiency LED6000 LED driver able tosource up to 3 ADC current, and a certified SPBTLE-1S Bluetooth Low Energymodule, compliant with BT specifications v4.2 and BQE qualified.

The STSW-POEL45FW board firmware is programmed via the STSW-BNRG1STLINK utility.
