LT3595AEUHH#PBF

LED Driver IC Overview

The LT3595AEUHH#PBF is a 16-channel LED driver IC from Analog Devices Inc., designed for high-density lighting applications. It operates in buck mode with a supply voltage range of 3V to 5.5V and delivers up to 50mA per channel. The device features a switching frequency of 2MHz and supports PWM dimming. It is housed in a 56-pin QFN (5x9) package with an exposed pad, offering a compact solution for multi-segment LED arrays.

LED Driver IC Feature Summary

• Integrates 16 independent current-regulated channels for uniform LED brightness control
• Supports high-frequency PWM dimming for flicker-free operation
• Utilizes synchronous buck topology to maximize power efficiency across the load

LED Driver IC Applications

• High-density LCD backlight systems requiring multiple segment zones
• Portable electronic devices with space-constrained lighting requirements
• Automotive interior illumination modules

LED Driver IC Procurement Notes

Verify the specific suffix 'EUHH' corresponds to the required 56-QFN package variant and tape-and-reel or tube packaging preferences. Confirm that the 'A' grade designation meets the necessary temperature and performance specifications for the target application environment before finalizing orders.

LED Driver IC Selection Notes

Select this component when a single-IC solution is needed to drive up to 16 LED strings simultaneously. Ensure the input voltage source remains within the 3V to 5.5V operational window. Consider thermal management requirements due to the high channel count and the necessity of connecting the exposed pad for heat dissipation.

LED Driver IC Part Context

This part belongs to the LT3595 family of LED drivers, which are optimized for driving multiple LEDs from a low-voltage source. It replaces discrete transistor-based solutions, reducing board space and simplifying design complexity for manufacturers focusing on slim-profile consumer electronics and display technologies.

LED Driver IC Replacement Considerations

The LT3595EUHH#TRPBF offers identical electrical characteristics but utilizes a tape-and-reel packaging format instead of tubes, facilitating automated surface-mount assembly processes.
