LT3598IUF#TRPBF

LED Driver IC Overview

The LT3598IUF#TRPBF is a fixed-frequency boost DC/DC converter designed to drive up to six series-connected LED strings. It operates with an input voltage range of 2.7V to 5.5V and provides a regulated output current of 30mA per string. The device features 1.5% current matching across outputs and supports both analog dimming via the CTRL pin and PWM dimming. It utilizes a 24-lead QFN (4x4) package.

LED Driver IC Feature Summary

• Integrated boost topology for driving multiple high-voltage LED strings from low-voltage sources
• Precise current regulation with specified matching accuracy across all output channels
• Dual-mode dimming capability supporting both analog control and pulse-width modulation signals

LED Driver IC Applications

• Automotive exterior lighting systems requiring multi-string LED drivers
• Industrial illumination fixtures utilizing series-connected LED arrays
• Portable battery-powered lighting equipment needing efficient step-up conversion

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation remains Analog Devices Inc., formerly Linear Technology, to ensure authenticity. Check for RoHS compliance documentation as required by your assembly standards. Ensure the component matches the exact part number to avoid functional discrepancies in LED driver circuits.

LED Driver IC Selection Notes

Select this component when designing circuits that require independent regulation of multiple LED strings from a single power source. It is suitable for applications demanding high current matching accuracy without external resistor trimming. Consider the 24-lead QFN package for space-constrained designs requiring efficient thermal performance and compact footprint.
