LT3486IFE#PBF

LED Driver IC Overview

The LT3486IFE#PBF is a dual-channel white LED boost converter driver manufactured by Analog Devices Inc. It operates within an input voltage range of 2.5 V to 24 V and delivers up to 1.3 A output current per channel. The device utilizes a fixed switching frequency of 2.5 MHz and supports PWM dimming for brightness control. Packaged in a TSSOP-16, it functions as a synchronous step-up converter designed specifically for driving multiple white LEDs.

LED Driver IC Feature Summary

• Dual independent channels for simultaneous white LED drive
• Integrated high-frequency synchronous boost topology
• Supports precise pulse-width modulation dimming

LED Driver IC Applications

• White LED backlighting systems
• Portable electronic display illumination
• Automotive interior lighting modules

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging configuration. Confirm the TSSOP-16 package variant matches your PCB footprint requirements. Ensure the 2.5 MHz switching frequency aligns with your electromagnetic interference constraints and passive component selection. Validate that the 24 V maximum input rating suits your power supply architecture.

LED Driver IC Selection Notes

Select this component when dual-channel LED regulation is required from a single boost stage. The 2.5 MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the 1.3 A per channel current capability meets the total LED string requirements. Consider thermal performance in the TSSOP-16 package under continuous load conditions.

LED Driver IC Part Context

This part belongs to the LT3486 series of LED drivers. It is distinct from linear regulators like the LT3086 or buck converters such as the LT3430. The device serves as a specialized solution for boosting voltage to drive series-connected LED strings efficiently.

LED Driver IC Replacement Considerations

LT3486IFE#TRPBF offers identical electrical characteristics but uses tape-and-reel packaging instead of tubes.
