LED Driver IC datasheet and documents for LT3475EFE#PBF

LT3475EFE#PBF

LED Driver IC Overview

The LT3475EFE#PBF is a dual-channel step-down LED driver IC manufactured by Analog Devices Inc. It operates from a 4 V to 36 V input supply and delivers up to 1.5 A per channel. The device utilizes a buck topology with an adjustable switching frequency ranging from 200 kHz to 2 MHz. It features PWM dimming capability and open LED protection. The component is housed in a 20-lead TSSOP package with an exposed pad and functions within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

Dual independent output channels for driving multiple LED strings
Integrated PWM dimming control interface
Built-in protection against open LED conditions

LED Driver IC Applications

LED lighting driver circuits
General illumination systems
Portable lighting devices

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the TSSOP-20 package variant matches the target PCB footprint. Ensure the supplier provides valid traceability documentation for the Analog Devices brand. Cross-reference the datasheet revision date to confirm feature consistency.

LED Driver IC Selection Notes

Select this component when dual-channel current regulation is required from a single controller. The wide input voltage range supports various power sources. The adjustable frequency allows optimization for external inductor size. Verify that the thermal performance of the TSSOP package meets the application's heat dissipation requirements.

LED Driver IC Part Context

This part belongs to the LT3475 series of LED drivers. It is distinct from the LTC1475, which is a fixed-output buck converter, and the LT3965, which is an 8-switch matrix dimmer. The LT3475EFE#PBF specifically denotes the tube-packaged version of the dual-channel buck LED driver.
