LT3599IUH#TRPBF

LED Driver IC Overview

The LT3599IUH#TRPBF is a high-efficiency, fixed-frequency step-up DC/DC converter designed specifically for driving four strings of LEDs. It integrates a 2A internal power switch and supports output voltages up to 44V. The device provides precise current regulation with ±1.5% matching across all channels. It operates from an input voltage range of 3.1V to 30V and features both analog and PWM dimming capabilities. Packaged in a 32-lead QFN (5mm x 5mm) exposed pad package, it ensures reliable thermal performance.

LED Driver IC Feature Summary

Integrates a 2A internal power switch for compact LED driver designs
Provides four independent current-regulated outputs with ±1.5% matching accuracy
Supports flexible control via analog and pulse-width modulation (PWM) dimming interfaces

LED Driver IC Applications

Automotive exterior lighting systems
Industrial area and street lighting fixtures
High-brightness general illumination arrays

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the component matches the Analog Devices Inc. manufacturer designation. Ensure the 32-QFN package type aligns with your PCB footprint requirements. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

LED Driver IC Selection Notes

Select this component when designing multi-string LED applications requiring tight current matching without external resistors. It is suitable for boost topologies where input voltages vary between 3.1V and 30V. Consider the 32-QFN package for space-constrained layouts. Verify that the required output voltage does not exceed the 44V limit of the internal switch.

LED Driver IC Part Context

This part belongs to the LT3599 family of LED drivers from Analog Devices. It is distinct from other switching regulators by its specialized four-channel architecture optimized for LED string balancing. The device simplifies design by eliminating the need for individual current-sensing resistors per channel.
