LED Driver IC datasheet and documents for LT3474IFE#TRPBF

LT3474IFE#TRPBF

LED Driver IC Overview

The LT3474IFE#TRPBF is a high-efficiency, single-output buck LED driver IC manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5V to 36V and provides a regulated output current of 1A. The device supports PWM dimming control and features an adjustable switching frequency ranging from 200kHz to 2MHz. Packaged in a 16-lead TSSOP with exposed pad (TSSOP-EP), it is designed for automotive-grade applications and functions within a junction temperature range of -40°C to 125°C.

LED Driver IC Feature Summary

Integrates a synchronous buck converter topology with an internal power switch for efficient LED regulation.
Supports wide-range PWM dimming control for precise brightness adjustment.
Features an adjustable switching frequency to optimize external component size and performance.
Includes thermal shutdown protection to safeguard the device during overload conditions.

LED Driver IC Applications

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the automotive-grade qualification aligns with your system requirements. Ensure the 16-TSSOP-EP footprint matches your PCB layout constraints. Cross-reference the datasheet for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

LED Driver IC Selection Notes

Select this component when a single-channel, 1A constant current source is required for LED loads. The wide input voltage range accommodates various supply rails common in automotive environments. Choose this part over non-synchronous alternatives if higher efficiency at lower input voltages is critical. Verify that the desired switching frequency falls within the 200kHz to 2MHz range to meet EMI and inductor size constraints.

LED Driver IC Part Context

This part belongs to the LT3474 family of LED drivers from Analog Devices. It shares core functionality with the LT3474IFE#PBF but differs in packaging format. The series is characterized by its robust automotive-grade design and integrated synchronous rectification, distinguishing it from older linear or non-synchronous switching LED drivers in the manufacturer's portfolio.
