产品概要
描述
The 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 35 W maximum and a LED voltage in the range of 24 - 48 V with a constant current regulation of 0.7 A.
The power board can provide 3.3 V supply voltage (J12 pin 1) to the connectivity board (connected via J12) and to a common GND (J12 pin 4).
Thanks to the embedded programmable BlueNRG-M2SP, the connectivity board can manage the enable/disable state (J12 pin 3) and the PWM dimming (J12 pin 2) signals.
