The LT3745EUJ-1#PBF from 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. It offers individual 6-bit dot correction current adjustment and 12-bit grayscale PWM dimming for each channel, accessible via an LVDS serial data interface.
Key electrical specifications include a wide 6V to 55V power input voltage range and 16 independent LED outputs capable of up to 75mA at 36V. The LED current matching is typically ±4% at 50mA, with a minimum LED on-time of 0.5µs. The switching frequency can range from 200kHz to 1MHz.
This component is housed in a 40-lead 6mm x 6mm QFN package with an exposed pad, suitable for surface mounting. It operates within a temperature range of -40°C to 125°C (TJ). The LT3745EUJ-1#PBF is well-suited for applications such as large screen display LED backlighting, mono-, multi-, and full-color LED displays, as well as LED billboards and signboards. It also provides full diagnostic and protection features against open/short LED and overtemperature faults.
