The LT3745EUJ#PBF from LT is a versatile 16-channel LED driver featuring an integrated 55V buck controller. This device is designed to drive up to 75mA per channel at 36V, making it suitable for demanding backlighting applications.
Key features include individual 6-bit dot correction for precise current adjustment and 12-bit grayscale PWM dimming for high-resolution control. The buck controller generates an adaptive bus voltage, optimizing efficiency for parallel LED strings. A fast 0.5µs minimum LED on-time and a cascadable 30MHz serial data interface are also included.
This LED driver provides comprehensive diagnostic and protection features, including detection for open/short LEDs and overtemperature faults. The fault status is communicated via the serial data interface. The LT3745EUJ#PBF is housed in a 40-lead 6mm x 6mm QFN package, suitable for surface mounting.
Applications include large screen display LED backlighting, mono-, multi-, and full-color LED displays, and LED billboards and signboards. Its robust design and advanced features make it an excellent choice for high-performance LED lighting solutions.
The power input VIN ranges from 42V to 55V, and the logic supply VCC ranges from 3V to 5.5V.
