LED Driver IC datasheet and documents for LTC3490ES8#TRPBF

LTC3490ES8#TRPBF

LED Driver IC Overview

The LTC3490ES8#TRPBF is a high-efficiency boost converter-based LED driver IC manufactured by Analog Devices Inc. It operates from one or two NiMH or alkaline cells, generating a constant current of up to 350mA with a compliance voltage of up to 4V. The device features an integrated 1.3MHz switching frequency and supports analog dimming. It is housed in an 8-SOIC package (0.154" width) and operates within a temperature range of -40°C to +85°C. The supply current is specified at 30,000uA.

LED Driver IC Feature Summary

Integrates a high-efficiency boost converter topology for single-cell operation
Provides configurable constant current output without requiring a microcontroller
Supports analog dimming control via logic level input

LED Driver IC Applications

Portable LED lighting systems powered by single-cell batteries
Flashlight applications requiring high efficiency from alkaline or NiMH sources
Compact indicator lights in battery-operated consumer electronics

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm that the ES8 variant corresponds to the standard SOIC-8 package dimensions. Ensure compatibility with the required operating temperature range for the intended environment. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid counterfeit components.

LED Driver IC Selection Notes

Select this component for designs requiring a simple, microcontroller-free solution for driving LEDs from low-voltage sources. The fixed 1.3MHz frequency allows for small external passive components. Consider the 350mA maximum current limit and 4V compliance voltage when sizing the LED string. The analog dimming feature requires appropriate logic level interfacing.

LED Driver IC Part Context

This part belongs to the LTC3490 series of LED drivers designed for portable applications. It simplifies power management by integrating the boost converter and current regulation into a single compact package. The ES8 designation specifies the surface-mount plastic package type suitable for automated assembly processes.
