STEVAL-POEL45W1: 45W PoE LED Driver with BLE Control
The STEVAL–POEL45W1 is a PoE-enabled constant current LED driver with a PM8805 Power over Ethernet interface, LED6000 LED driver and Bluetooth module SPBTLE-1S for smart dimming control.
The PM8805 is a highly integrated device, embedding a double active bridge, a hot-swap MOSFET and an IEEE802.3bt-compliant Powered Device (PD) PoE interface.
The LED6000 is a step-down monolithic switching regulator designed to source up to 3 ADC current for high power LED driving. The 250 mV 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, compliant with BT specifications v4.2 and BQE qualified.
The STEVAL–POEL45W1 evaluation board is designed to provide a power output of 48 W and can dim LEDs down to 1% of the maximum brightness without any flicker. Remote on/off and dimming control can be managed through the PoE Lighting android application available free of charge on the Google Play store.
