• Supports analog and PWM dimming control methods
• Step-up (boost) topology for efficient voltage conversion

LED Driver IC Applications

• LED backlight systems
• Electronic display backlighting
• Portable device illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging if required for automated assembly. Confirm the manufacturer status as Microsemi Corporation, now part of Microchip Technology. Check for obsolete status indicators on distributor platforms, as some listings may reflect discontinued inventory. Ensure compatibility with 8-TSSOP footprint requirements during PCB design review.

LED Driver IC Selection Notes

Select this component when a boost converter is needed for low-voltage LED strings. Verify input voltage stability within the 1.6V to 6V range. Consider the 150mA output limit for LED array sizing. Ensure thermal management aligns with TSSOP-8 package constraints. Validate dimming interface compatibility with the host controller's analog or PWM signals.

LED Driver IC Part Context

This part belongs to the LX1992 series of high-efficiency LED drivers from Microsemi. The series targets portable electronics requiring compact power solutions. The LX1992CDU-TR variant specifically denotes the tape-and-reel packaging format. It represents a specialized solution for integrated backlight control rather than general-purpose power management.

LED Driver IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with Microchip's official replacement guides for legacy Microsemi components. Verify pinout and electrical parameter compatibility before substitution.
