LT3595EUHH#TRPBF

LED Driver IC Overview

The LT3595EUHH#TRPBF is a monolithic 16-channel buck mode LED driver designed for high-performance lighting applications. It integrates a dual synchronous step-down DC-DC converter architecture to regulate current across sixteen independent channels. The device supports an input voltage range of 3V to 42V and delivers a typical output current of 50mA per channel. It features PWM dimming capability with a frequency range up to 1MHz and operates within a temperature range of -40°C to +125°C. Packaged in a 56-lead QFN (5x9mm) format, it provides precise current regulation for complex LED arrays.

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the part number corresponds to the Linear Technology division of Analog Devices Inc., as legacy branding may appear on older documentation. Ensure compatibility with the intended PCB footprint, specifically the 56-lead QFN package dimensions. Cross-reference the datasheet revision date to ensure all electrical specifications match the production batch requirements.

LED Driver IC Selection Notes

Select this component when designing systems requiring independent current regulation for up to sixteen LEDs from a single IC. Consider the thermal performance of the exposed pad QFN package for high-power density applications. Evaluate the input voltage range against the available power source to ensure stable operation. Verify that the required dimming frequency falls within the supported range for the application's flicker-free performance standards.

LED Driver IC Part Context

The LT3595 series represents a family of multi-channel LED drivers optimized for automotive and industrial use. The EUHH variant specifically denotes the 56-lead QFN package suitable for surface-mount assembly. This part complements other single or dual-channel drivers by offering higher integration density, reducing board space and component count for large LED arrays.

LED Driver IC Replacement Considerations
