LED Driver IC datasheet and documents for LT3598EFE#PBF

LT3598EFE#PBF

LED Driver IC Overview

The LT3598EFE#PBF is a fixed frequency step-up DC/DC converter designed to drive up to six strings of LEDs at an output voltage up to 44V. It regulates LED current accurately even when the input voltage exceeds the LED output voltage. The device supports analog dimming on the CTRL pin and pulse width modulation (PWM) dimming on the PWM pin, delivering up to a 3000:1 dimming ratio. The switching frequency is programmable from 200kHz to 2.5MHz via an external resistor. It features 1.5% accurate LED current matching and operates with a wide input voltage range of 3.2V to 30V.

LED Driver IC Feature Summary

Provides True Color PWM dimming for high contrast ratios
Ensures precise current regulation across multiple LED strings
Supports synchronization to an external clock signal
Includes programmable overvoltage protection and thermal derating

LED Driver IC Applications

LCD backlighting for consumer electronics
Industrial Human-Machine Interface (HMI) displays
Medical device illumination systems
Automotive display lighting applications

LED Driver IC Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the ordering part number matches the required automotive or industrial temperature grade if applicable to your design constraints.

LED Driver IC Selection Notes

Select this component for designs requiring independent control of up to six LED strings with high current matching accuracy. It is suitable for applications where the input voltage may vary significantly relative to the LED forward voltage. Consider the programmable switching frequency range when optimizing for electromagnetic interference and inductor size constraints.

LED Driver IC Part Context

This device belongs to the LT3598 family of LED drivers manufactured by Analog Devices Inc. It is distinct from similar models like the LT3599, which offers different channel counts and current capabilities. The EFE suffix indicates a specific thermally enhanced package configuration suitable for surface mount assembly.
