LT3599HFE

LED Driver IC Overview

The LT3599HFE is a high-performance LED driver IC designed for regulating multiple LED strings. It features four independent current channels, each capable of delivering up to 120mA with precise matching. The device integrates a boost converter operating at frequencies between 200kHz and 2.1MHz, supporting analog and PWM dimming methods. It operates within a wide temperature range of -40°C to 150°C and utilizes a 28-pin TSSOP package with an exposed pad for thermal management.

LED Driver IC Feature Summary

• Four independent regulated current outputs for multi-string LED applications
• Integrated step-up DC-DC converter for efficient power regulation
• Supports both analog and pulse-width modulation (PWM) dimming control
• High current matching accuracy across all output channels

LED Driver IC Applications

• LED lighting systems requiring multi-channel regulation
• Display backlighting for industrial or commercial displays
• Indicator control circuits in automotive or consumer electronics
• General-purpose LED string drivers where current matching is critical

LED Driver IC Procurement Notes

Verify the exact ordering suffix (e.g., #PBF for tube, #TRPBF for tape and reel) against the manufacturer's official datasheet to ensure correct packaging and availability. Confirm that the 28-TSSOP-EP package matches your PCB footprint requirements. Cross-reference the part number with Analog Devices Inc. authorized distributors to avoid counterfeit components.

LED Driver IC Selection Notes

Select this component when designing circuits that require precise current regulation for four separate LED strings. Ensure the input voltage and load conditions fall within the operational limits of the integrated boost converter. Consider thermal performance due to the exposed pad design, which aids in heat dissipation during continuous operation at higher currents.
