LT3745IUJ#PBF Description

Short technical summary and product information.

The LT3745IUJ#PBF by Analog Devices Inc. is a versatile 16-channel LED driver integrated with a 55V buck controller. This device is designed to drive up to 75mA per channel at 36V, making it suitable for demanding LED applications.

 

Key features include individual 6-bit dot correction current adjustment and 12-bit grayscale PWM dimming for precise control. The LED driver boasts ±3% current matching at 50mA and a minimum LED on-time of 0.5µs. It also incorporates full diagnostic and protection features against open/short LEDs and overtemperature faults.

 

The LT3745IUJ#PBF utilizes an adaptive LED bus voltage for high efficiency and features a cascadable 30MHz serial data interface. This interface allows for easy integration into large screen LCD dynamic backlighting systems, as well as mono-, multi-, and full-color LED displays.

 

Packaged in a 40-lead 6mm x 6mm QFN, this LED driver is designed for surface mount applications. Its robust feature set makes it an excellent choice for LED billboards, signboards, and large-format displays.
