1 STEVAL-ILL0V Smart home lighting based on HVLEDPF and SPSGRF Data brief Description The STEVAL-ILL0V evaluation board is an offline LED driver based on the HVLEDPF, coupled with Sub-GHz connectivity based on the SPSGRF- low power programmable RF transceiver module. The interface between the HVLEDPF and the SPSGRF is managed by an STML0 ultra-low-power ARM Cortex -M0+ MCU. The microcontroller and connectivity module are supplied by the LED driver through an auxiliary winding. The LED driver evaluation board can operate in standalone mode in communication with the bundled STEVAL-ILL0V_Remote controller based on SPML to help to reduce development and certification time. The board can also be rendered visible to cloud applications with the addition of a wireless bridge. Features LED driver features: 0 W flyback converter with quasiresonant operation Primary side regulation, no optocoupler required High power factor and low THD Open circuit and short-circuit LED management ±% LED current regulation Dimming range:.% to 00% Sub-GHz connectivity features: Works with the bundled STEVAL- ILL0V_remote controller based on SPML- sub-ghz module Allows remote lamp powering on and off Allows lamp remote dimming Standby power consumption: < 0.
