LED Driver IC datasheet and documents for LT3491EDC#PBF

LT3491EDC#PBF

LED Driver IC Overview

The LT3491EDC#PBF is a fixed-frequency boost DC/DC converter designed to drive up to six series-connected white LEDs from a single lithium-ion cell. It operates within an input voltage range of 2.5V to 12V and delivers a regulated output current of 2mA. The device integrates a Schottky diode and functions at a switching frequency of 2.3MHz. It supports supply voltages of 3.3V, 5V, and 9V typical applications, with a maximum supply current of 4000uA. The component is housed in a 6-pin DFN EP package measuring 2mm x 2mm with a height of 0.75mm.

LED Driver IC Feature Summary

Integrates an internal Schottky diode to minimize external component count
Provides constant current regulation for multiple series-connected white LEDs
Operates efficiently from a single-cell lithium-ion battery source

LED Driver IC Applications

Mobile phone backlighting systems
Portable electronic device illumination
Battery-powered LED lighting modules

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status before procurement. Confirm the 6-pin DFN EP package dimensions match the target PCB footprint. Ensure the supplier provides valid traceability documentation for the Analog Devices manufacturer. Check for any recent product change notices that may affect pinout or electrical characteristics.

LED Driver IC Selection Notes

Select this component when driving six series white LEDs from a single-cell lithium source is required. The integrated Schottky diode reduces board space compared to discrete solutions. Verify that the 2.3MHz switching frequency aligns with EMI constraints. Ensure the 2mA output current meets the brightness requirements of the target LED array.

LED Driver IC Part Context

This part belongs to the LT3491 family of LED drivers from Analog Devices. It shares functional similarities with variants like LT3491ESC8 but differs in package type and segment support. The family targets portable applications requiring efficient power conversion from low-voltage sources to drive high-brightness LED loads.
