LX23224IDB

LED Driver IC Overview

The LX23224IDB is a four-channel LED driver controller manufactured by Microsemi Corporation. It employs Flyback and Step-Up (Boost) topologies for edge-lit LED display applications. The device operates within a supply voltage range of 15V to 40V and supports an operating temperature range of -40°C to 85°C. It is housed in a 36-BSOP package with a width of 7.50mm. The component features PWM control and includes an integrated DC/DC PSU controller.

LED Driver IC Feature Summary

• Provides independent control for four output channels suitable for edge-lit displays
• Integrates Flyback and Boost topology capabilities for efficient power conversion
• Includes built-in DC/DC power supply unit controller functionality

LED Driver IC Applications

• Edge-lit LED display systems

LED Driver IC Procurement Notes

Verify the specific suffix, as LX23224IDB-TR indicates tape-and-reel packaging while the base part may differ. Confirm availability status as this component is listed as obsolete or discontinued in multiple distributor records. Ensure compatibility with existing PCB footprints for the 36-BSOP package before procurement.

LED Driver IC Selection Notes

Select this component for applications requiring four independent LED channels driven by a combined Flyback and Boost architecture. It is appropriate for designs needing an integrated PSU controller alongside LED driving functions. Consider the surface-mount 36-BSOP package constraints and the specified voltage and temperature ranges during system design.

LED Driver IC Part Context

This part belongs to the Microsemi LX23224 series of LED drivers. It is designed specifically for high-performance lighting control where multiple channels must be managed efficiently. The integration of power supply control reduces external component count compared to discrete solutions.

LED Driver IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility with alternative four-channel LED controllers if sourcing from different manufacturers.
