MP3388DR-LF-P

Overview

The MP3388DR-LF-P is an 8-channel boost WLED driver IC from Monolithic Power Systems. It operates with a 4.5V to 25V input voltage and generates up to 50V output. The device features a QFN-24 package, 1.25MHz switching frequency, and supports PWM dimming. It includes protections for open/short LEDs, overvoltage, and overtemperature.

Feature Summary

• Provides balanced current driving for eight parallel white LED strings
• Supports flexible brightness control via external PWM or DC input signals
• Integrates comprehensive protection mechanisms including thermal shutdown

Applications

• LCD panel backlighting systems
• High-brightness LED arrays
• Portable electronic display modules

Procurement Notes

Verify the NRND status before procurement as this component is not recommended for new designs. Confirm the specific suffix DR-LF-P matches your required packaging and lead time constraints. Ensure compatibility with existing circuit layouts due to potential obsolescence risks associated with end-of-life products.

Selection Notes

Select this part for applications requiring eight independent LED channels within a compact footprint. Consider the MP3388S series as a modern alternative for new designs. Evaluate the 4.5V to 25V input range against your system power supply capabilities. Verify thermal management requirements given the QFN-24 package constraints.

Part Context

This component belongs to the MP3388 family of LED lighting drivers designed for high-efficiency backlighting. It utilizes a fixed-frequency current control mode to regulate LED currents accurately. The family targets mobile and portable devices where space and power efficiency are critical design parameters.

Replacement Considerations

Public documentation identifies MP3388S as the recommended alternative for new designs. Verify pinout compatibility and electrical specifications when transitioning from the MP3388DR-LF-P to ensure seamless integration without redesigning the PCB layout.
