LX27902DW-TR

LED Driver IC Overview

The LX27902DW-TR is a high-performance power management integrated circuit manufactured by Microsemi Corporation. It functions as an LED driver controller with pulse-width modulation (PWM) capabilities, housed in a compact 24-SOIC package. The device supports dimming via analog or PWM signals and operates at a switching frequency of 1MHz. Designed for efficient power regulation, it features a maximum supply voltage rating of 27V and includes two distinct output channels to manage lighting loads effectively.

LED Driver IC Feature Summary

• Integrated PWM control for precise LED brightness adjustment
• Supports both analog and digital dimming signal inputs
• Dual-output architecture for versatile load management
• Compact surface-mount packaging for space-constrained designs

LED Driver IC Applications

• General illumination systems requiring precise light control
• Automotive interior and exterior lighting modules
• Commercial building lighting infrastructure
• Portable electronic display backlighting units

LED Driver IC Procurement Notes

Verify the specific suffix DW-TR against official Microsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and thermal management requirements before integration. Cross-reference the manufacturer part number with current distributor listings to confirm availability status and authenticity, as component revisions may affect pinout or electrical characteristics.

LED Driver IC Selection Notes

Select this component when dual-channel LED driving with integrated PWM control is required within a 27V supply limit. Consider the 24-SOIC package constraints for board layout and thermal dissipation needs. Evaluate whether the 1MHz operating frequency aligns with electromagnetic interference standards for the target application environment compared to lower-frequency alternatives.

LED Driver IC Part Context

This part belongs to the LX27xx series of LED driver controllers from Microsemi, designed for efficient power management in lighting applications. The series typically offers integrated solutions for dimming and regulation, reducing external component count. The LX27902 variant specifically provides dual outputs, distinguishing it from single-channel counterparts in the same family.

LED Driver IC Replacement Considerations
