MP3386DR-LF-P

Overview

The MP3386DR-LF-P is a six-channel white LED driver IC from Monolithic Power Systems, utilizing a boost topology. It operates within an input voltage range of 4.5 V to 25 V and supports output voltages up to 50 V. The device functions at a switching frequency of 1.25 MHz and is housed in a QFN-24 package. It is rated for temperatures between -40°C and +85°C.

Feature Summary

• Integrates six independent output channels for multi-zone LED control
• Employs a high-frequency boost converter architecture for efficient power management
• Supports PWM dimming capabilities for brightness adjustment

Applications

• White LED backlighting systems
• Multi-zone LED lighting arrays
• Portable electronic display illumination

Procurement Notes

Verify the lifecycle status before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm that the QFN-24 package and specific electrical parameters align with current design requirements. Ensure compliance with RoHS standards and check for alternative components if long-term supply stability is critical for the project.

Selection Notes

Select this driver for applications requiring multiple synchronized LED outputs from a single boost stage. The 1.25 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the NRND status when planning for future production runs, evaluating whether existing inventory suffices or if a newer generation replacement is necessary.

Part Context

This part belongs to the MP3386 series of LED lighting drivers from Monolithic Power Systems. It is specifically engineered for driving white LEDs in portable devices. The DR suffix indicates the tape and reel packaging format, while LF-P denotes lead-free and Pb-free construction compliant with environmental directives.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, consult manufacturer resources for potential next-generation replacements.
