MP3371GR-0000-Z

Overview

The MP3371GR-0000-Z is an 8-channel synchronous boost WLED driver from Monolithic Power Systems. It features a maximum output current of 50mA per channel and operates with a typical switching frequency of 650kHz. The device supports an I2C interface for control and includes a shutdown function. It is housed in a 24-QFN (4x4) package, designed for surface mount installation. The component handles input voltages up to 30V and generates output voltages up to 50V, suitable for driving white LED arrays in portable electronics.

Feature Summary

Eight independent current channels for precise LED regulation
Synchronous boost topology for high efficiency
I2C digital interface for configuration and dimming control

Applications

Smartphone LCD panel backlighting
Tablet display illumination
Portable electronic device lighting systems

Procurement Notes

Verify the specific suffix Z indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm the 24-QFN package dimensions match your PCB footprint requirements. Ensure I2C address settings align with your system bus architecture before integration.

Selection Notes

Select this component when eight distinct LED channels are required within a compact form factor. The I2C interface simplifies control logic compared to analog alternatives. Consider the 50mA per channel limit against total brightness requirements. The synchronous design offers better efficiency than asynchronous counterparts at similar current levels.

Part Context

This part belongs to the MP3371 series of WLED drivers. It shares functional similarities with other MPS boost controllers but is distinguished by its eight-channel capability and digital I2C control. It serves as a specialized solution for multi-zone or uniform backlighting applications where space is constrained.

Replacement Considerations

Direct substitutes include the MP3371GR-0000-P variant, which shares identical electrical characteristics and pinout. Other MPS models like the MP3373GM-Z offer more channels but differ in package and current ratings. Verify compatibility if replacing with non-MPS components due to interface differences.
