LT3486EFE#PBF

LED Driver IC Overview

The LT3486EFE#PBF is a dual-channel white LED boost converter driver manufactured by Analog Devices Inc. It operates from a single supply voltage and integrates two independent high-current sinks capable of delivering up to 1.3A each. The device features a wide input voltage range and supports PWM dimming for brightness control. Packaged in a 16-lead TSSOP with an exposed pad, it includes internal switching transistors and protection features such as thermal shutdown and open LED detection.

LED Driver IC Feature Summary

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the package type matches the design footprint requirements. Check for any recent product change notifications or lifecycle status updates from the manufacturer to ensure long-term availability.

LED Driver IC Selection Notes

Select this component when dual-channel LED driving is required within a compact surface-mount footprint. Ensure the input voltage range aligns with the system power supply. Consider the thermal performance of the TSSOP-16 package relative to the expected load current and ambient temperature conditions during operation.

LED Driver IC Part Context

This part belongs to the LT3486 family of LED drivers designed for portable applications. It complements other Analog Devices power management solutions by providing dedicated lighting control capabilities. The device is distinct from general-purpose DC-DC converters due to its integrated LED-specific protection and current regulation features.

LED Driver IC Replacement Considerations

Consult official Analog Devices documentation for verified pin-compatible or functionally equivalent alternatives. Cross-reference specifications such as output current capability and operating voltage range to ensure compatibility.
