MP3364GR-P

LED Driver IC Overview

The MP3364GR-P is a Monolithic Power Systems LED lighting driver IC featuring a boost topology with four output channels. It supports a maximum channel current of 150 mA and operates within an input voltage range of 3.5 V to 36 V. The device utilizes a 2.2 MHz switching frequency and provides a dimming ratio of 15000:1 via I2C interface. Packaged in a QFN-24 format, it functions as a white LED driver for backlighting applications.

LED Driver IC Feature Summary

• Integrates four independent current source channels for driving white LED arrays
• Supports high contrast dimming through a 15000:1 ratio capability
• Includes open LED protection mechanisms for system reliability

LED Driver IC Applications

• Backlighting for small LCD panels
• Backlighting for medium-sized LCD panels
• White LED array illumination systems

LED Driver IC Procurement Notes

Verify the specific suffix GR-P against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure the design environment supports the required 3.5 V to 36 V input range and that thermal management aligns with the component's power dissipation limits under expected load conditions.

LED Driver IC Selection Notes

Select this component when designing multi-channel white LED backlights requiring precise current regulation and digital control. The integrated I2C interface simplifies brightness adjustment compared to analog-only solutions. Consider the QFN-24 footprint for space-constrained PCB layouts while ensuring adequate thermal relief for the operating temperature range.

LED Driver IC Part Context

This part belongs to the MP3364 series of LED drivers from Monolithic Power Systems. It is specifically engineered for step-up conversion to drive multiple LEDs in series or parallel configurations. The series focuses on providing efficient power management for display backlighting with integrated protection features.

LED Driver IC Replacement Considerations

Consult MPS documentation for direct pin-compatible alternatives within the MP336x family. Verify that any substitute maintains the 4-channel architecture and I2C compatibility if digital control is required by the host system.
