The driver uses a constant-current buck topology for each channel. A reference voltage and external resistor set the full-scale current. PWM dimming modulates the enable signal at up to 25kHz for flicker-free operation. Analog dimming adjusts the reference voltage via an external DAC or potentiometer. Open LED detection monitors output voltage; short LED detection monitors current sense voltage. Thermal shutdown protects at 150C junction.<\/p>\n
