LT^®3746 Integrated one32passageLEDDrive and one55VBuck controller.LEDThe driver can light up to each channel30mA/13Vof tandemLED, while the buck controller generates an adaptive bus voltage for the parallel connectionLEDString power. Each channel has a separate one6Site correction current regulation sum12bit grayscale levelPWMDimming capability. Both point correction and grayscale grade can passTTL / CMOSA serial data interface in the logic circuit is obtained.

LT3746Available for targetingLEDOpen / Comprehensive diagnosis and protection for short circuit and overheating faults. The fault state is looped through the serial data interface.30MHzThe fully buffered, slew rate balanced, and cascadable serial data interface make the chip ideal for large screensLCDdynamic back lighting as well as monochrome, multicolor, and full-colorLEDDisplay.
