Evaluation Board , HVLED001B, Smart LED Driver, Indoor Lighting

STEVAL-LLL012V1 smart LED driver reference design is composed of a power board and a connectivity board. The power board is a single stage LED driver with high power factor (HPF) and low total harmonic distortion (THD) tailored to LED power supply specifications for smart home lighting applications. On the primary side, the HVLED001B controller manages the AC-DC HPF flyback converter. Primary side regulation and optocoupler control are applied independently on the chip, both exploiting precise regulation and very low standby power under no load conditions. The converter supplies a power output of 35W maximum and a LED voltage in the range of 24 - 48V with a constant current regulation of 0.7A.

• 35 W LED driver with high power factor (HPF) flyback and constant current (CC) secondary regulation
• Wireless connectivity using BLE module
• ST BLE Mesh mobile app support
• Accepts remote on
• off and PWM dimming commands (10 -100%)
• THD < 15%, PF > 0.95 at full load for wide range input
• Efficiency is greater than 90%
• Standby consumption is less than 0.5W
