LT3598IFE#TRPBF

LED Driver IC Overview

The LT3598IFE#TRPBF is a fixed-frequency step-up DC/DC converter designed to drive up to six strings of LEDs with an output voltage capability of up to 44V. It operates within a switching frequency range of 200kHz to 2.5MHz and supports both analog and PWM dimming methods. The device features a junction temperature operating range from -40°C to 125°C and utilizes a surface-mount package.

LED Driver IC Feature Summary

• Integrated boost topology for driving multiple LED strings
• Supports analog and pulse-width modulation dimming control
• High current matching accuracy across output channels

LED Driver IC Applications

• LED lighting driver ICs
• Multi-string LED backlighting systems
• Automotive interior lighting applications

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Analog Devices documentation prior to integration. Ensure the supplier provides valid traceability data for automotive-grade components if required by the application specification.

LED Driver IC Selection Notes

Select this component for designs requiring independent regulation of up to six LED strings. The wide input voltage range and high output voltage capability make it suitable for series-connected LED arrays. Consider thermal management requirements given the 125°C maximum junction temperature rating.

LED Driver IC Part Context

This part belongs to the LT3598 family of LED drivers manufactured by Analog Devices Inc. It is functionally similar to the LT3598IFE#PBF, differing primarily in packaging format. The device integrates a power switch and control circuitry into a single compact solution for efficient LED illumination.

LED Driver IC Replacement Considerations

LT3598IFE#PBF serves as a direct pin-compatible alternative with identical electrical characteristics but differs in reel versus tube packaging.
