The LT3754IUH#TRPBF is a versatile 16-channel LED driver IC manufactured by Analog Devices, designed for applications such as automotive, notebook, and TV monitor backlighting. It functions as a step-up DC/DC controller, capable of driving up to 45V of LEDs per string at a maximum of 50mA per channel. The device offers precise current matching of ±2.8% at 20mA and supports both PWM and analog dimming with ranges up to 3000:1 and 25:1, respectively.
Key features include a wide input voltage range from 6V to 40V, programmable operating frequency from 100kHz to 1MHz, and protection for open LED strings. The LT3754IUH#TRPBF is housed in a thermally enhanced 5mm x 5mm 32-pin QFN package, suitable for surface mounting. Its design adapts output voltage to LED forward voltage variations for optimal efficiency and includes features like programmable LED current derating versus temperature and an internal soft-start.
This LED driver is ideal for designs requiring multiple LED strings with accurate current control and dimming capabilities. The 32-WFQFN exposed pad package ensures good thermal performance, critical for high-power LED driving applications. The device also provides a fault flag for open LED conditions, enhancing system reliability.
