MP3376AGR-XXXX-P

Overview

The MP3376AGR-XXXX-P is an 8-channel synchronous boost WLED driver from Monolithic Power Systems. It features an I2C interface for control and operates within a supply voltage range of 3V to 5.5V. The device supports output voltages up to 50V and includes integrated switches. It functions as a DC/DC regulator with step-up topology, designed for high-speed LED driving applications.

Feature Summary

• Eight-channel synchronous boost architecture for multi-string LED arrays
• I2C digital interface for precise configuration and dimming control
• Integrated power switches eliminate external inductor requirements in some configurations

Applications

• LCD backlighting for mobile devices
• High-brightness LED illumination systems
• Portable electronic display modules

Procurement Notes

Verify the specific suffix variant against the manufacturer datasheet to ensure compatibility with required channel configurations and thermal performance. Confirm package type and pinout alignment with PCB layout specifications before integration.

Selection Notes

Select this component for designs requiring independent control of multiple LED strings via digital interface. Ensure input voltage ranges match system power rails and verify thermal dissipation capabilities for the target operating environment.

Part Context

This part belongs to the MP3376 series of WLED drivers. It is distinct from single or dual-channel variants by offering eight independent outputs. The series targets compact portable electronics where space efficiency and digital control are prioritized.

Replacement Considerations

Direct substitutes include other MPS 8-channel WLED drivers with I2C interfaces. Verify equivalent channel count, voltage ratings, and package dimensions when evaluating alternative sources.
