MP3384LGQ-P

Overview

The MP3384LGQ-P is a boost converter LED driver IC from the MP3384L series, designed for LCD backlighting applications. It supports up to four white LED strings with an input voltage range of 3V to 25V and a maximum output voltage of 50V. The device features an adjustable switching frequency of 625kHz or 1.25MHz and operates within a temperature range of -40°C to +125°C. It utilizes a QFN-16 (3mm x 3mm) package.

Feature Summary

Provides independent current regulation for four internal LED current sources with high matching precision between channels.
Supports PWM dimming control for brightness adjustment.
Integrates comprehensive protection mechanisms including overvoltage, undervoltage lockout, thermal shutdown, and LED open/short circuit detection.

Applications

LCD backlighting for portable devices
White LED string drivers in mobile displays

Procurement Notes

Verify the specific suffix 'P' against the manufacturer's official documentation to confirm packaging details and RoHS compliance status. Ensure the ordering information matches the exact part number MP3384LGQ-P to avoid discrepancies in pinout or electrical characteristics compared to other variants in the MP3384L family.

Selection Notes

Select this component when a low input voltage range starting at 3V is required for single-cell battery operation. The choice is driven by the need for precise current balancing across multiple LED strings and the requirement for a compact QFN-16 footprint. Consider the available switching frequencies to optimize external component size and efficiency.

Part Context

This part belongs to the MP3384L series of LED lighting driver ICs manufactured by Monolithic Power Systems. The series focuses on efficient power conversion for white LED applications, offering integrated solutions for controlling multiple LED strings in display backlighting systems with minimal external components.
