The LT3745-1 integrates a 16-channel LED driver with a 55V buck controller. The LED driver lights up to 75mA/36V of LEDs in series per channel, and the buck controller generates an adaptive bus voltage supplying the parallel LED strings. Each channel has individual 6-bit dot correction current adjustment and 12-bit grayscale PWM dimming. Both dot correction and grayscale are accessible via a serial data interface in LVDS logic. A ±4% LED current matching and a 0.5μs minimum LED on-time can be achieved at 50mA per channel.The LT3745-1 performs full diagnostic and protection against open/short LED and overtemperature fault. The fault status is sent back through the serial data interface. The 30MHz fully buffered, cascadable LVDS serial data interface makes the chip extremely suitable for large screen LCD dynamic backlighting and mono-, multi-, full-color LED displays. The LT3745 uses a TTL/CMOS serial data interface instead of LVDS.
