LT3595EUHH#PBF

LED Driver IC Overview

The LT3595EUHH#PBF is a 16-channel buck mode LED driver manufactured by Analog Devices Inc. It features independent current regulation for each channel, supporting up to 50mA output current per channel. The device operates with an input voltage range of 3V to 45V and includes internal switches. It utilizes PWM dimming for brightness control and is housed in a 56-pin QFN package with an exposed pad for thermal management.

LED Driver IC Feature Summary

• Provides independent current regulation across 16 channels to ensure uniform LED brightness
• Integrates high-efficiency buck converters with internal power switches for each channel
• Supports wide input voltage range suitable for various automotive and industrial supply rails
• Enables precise brightness control through external PWM dimming interface

LED Driver IC Applications

• Automotive exterior lighting systems including headlights and taillights
• High-brightness LED display backlights requiring multi-channel regulation
• Industrial indicator lighting arrays with strict current matching requirements
• General-purpose LED illumination modules utilizing series-connected LED strings

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the 56-QFN package dimensions match your PCB footprint. Ensure the operating temperature range meets your application's environmental specifications. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

LED Driver IC Selection Notes

Select this component when 16 independent channels are required for LED current regulation. Consider the 50mA per channel limit for load sizing. Evaluate the 45V maximum input voltage against your system supply. The buck topology is suitable for applications where input voltage exceeds LED forward voltage sums.

LED Driver IC Part Context

This part belongs to the LT3595 family of 16-channel LED drivers from Analog Devices. It is designed for high-reliability applications requiring precise current matching. The EUHH suffix denotes the specific package type and tape/reel or tube configuration depending on the full part number variant.

LED Driver IC Replacement Considerations

Public confirmed substitute part numbers include LT3595EUHH-TRPBF for reel packaging variants. Direct replacements must maintain the 16-channel architecture and similar electrical characteristics. Verify pin compatibility and thermal performance before substitution.
