LT3466EFE#TRPBF

LED Driver IC Overview

The LT3466EFE#TRPBF is a dual white LED step-up converter and LED driver manufactured by Analog Devices Inc. It operates with an input voltage range of 2.7 V to 24 V and delivers up to 400 mA output current per channel. The device features a fixed 1 MHz switching frequency and supports PWM dimming for brightness control. It is housed in a 16-lead EFN package (TSSOP-16) and functions within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Dual independent boost converters designed for driving two strings of white LEDs
• Integrated high-frequency switching regulator eliminating the need for external inductors in some configurations
• Supports pulse-width modulation (PWM) dimming for precise brightness adjustment

LED Driver IC Applications

• Backlighting for mobile phones and handheld devices
• Camera flash illumination systems
• Portable electronic display lighting

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the EFN package variant matches the required footprint, as other pinouts like DFN exist within the same family. Ensure compatibility with the target system's input voltage constraints before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when dual-channel LED drive capability is required from a single IC. It is suitable for applications needing high efficiency and compact solution size. Compare against the LT3466EDD variants if a different package style is preferred for thermal or layout reasons.

LED Driver IC Part Context

This part belongs to the LT3466 family of dual white LED drivers. It shares core functionality with variants such as the LT3466EDD but differs in package type and pinout configuration. The EFE suffix specifically denotes the 16-lead EFN package, distinguishing it from other physical form factors available in the series.

LED Driver IC Replacement Considerations

LT3466EDD#TRPBF serves as a functional alternative with identical electrical characteristics but utilizes a 10-lead DFN package instead of the 16-lead EFN. Verify mechanical fit and pin compatibility before substitution.
