مبدأ العمل
Same architecture as KLR3012AR-BAO with bin-specific output current and brightness matching characteristics. The BBA bin offers tighter channel-to-channel current matching for more uniform RGB color mixing. Constant-current buck topology with integrated MOSFETs. Dimming is achieved through PWM modulation of the enable pin or analog adjustment of the reference voltage.
