LT3746EUHH#PBF

The LT®3746 integrates a 32-channel LED driver with a 55V
buck controller. The LED driver lights up to 30mA/13V 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.
The LT3746 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, skew-balanced, cascadable
serial data interface makes the chip extremely suitable
for large screen LCD dynamic backlighting and mono-,
multi-, full-color LED displays.
