The LT3745EUJ#PBF by Analog Devices is a versatile 16-channel LED driver integrated with a 55V buck controller. This device is designed to drive LEDs in series per channel, with the buck controller generating an adaptive bus voltage for parallel LED strings. Each channel supports individual 6-bit dot correction current adjustment and 12-bit grayscale PWM dimming, accessible via a serial data interface.
Key electrical specifications include an input voltage range of 6V to 55V and an output current capability of up to 75mA per channel. The device features ±3% LED current matching at 50mA and a minimum LED on-time of 0.5µs. It operates with a frequency range of 200kHz to 1MHz and includes a 30MHz cascadable serial data interface.
This LED driver is suitable for applications requiring precise current control and dimming, such as large screen LCD dynamic backlighting, mono-, multi-, and full-color LED displays, and LED billboards. The LT3745EUJ#PBF comes in a 40-QFN (6x6) surface mount package, designed for efficient thermal management with an exposed pad.
