產品總覽

The LT3745EUJ#PBF is 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 TTL/CMOS logic. A ±3% LED current matching and a 0.5µs minimum LED on-time can be achieved at 50mA per channel. The LT3745 performs full diagnostic and protection against open/short LED and over-temperature fault. The fault status is sent back through the serial data interface. The 30MHz fully-buffered, skew-balanced, cascadable serial data interface makes the chip extremely suitable for large screen LCD dynamic backlighting and mono, multi, full-colour LED displays.
  • Adaptive LED bus voltage for high efficiency
  • Full diagnostic and protection - Individual open/short LED and over-temperature fault
  • 0.5µs Minimum LED on-time
