MP3304CDD-LF-P

LED Driver IC Overview

The MP3304CDD-LF-P is a Monolithic Power Systems LED driver IC designed for white LED backlight applications. It operates as a boost DC-DC converter with an internal switch, supporting a maximum output voltage of 18V and a peak switch current of 1.33A. The device functions within a supply voltage range of 2.5V to 6V and utilizes a fixed switching frequency of 2.2MHz. It features PWM dimming control and is housed in an 8-QFN (2x3mm) package. The component supports an operating temperature range from -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a high-efficiency boost converter topology with an internal power switch for compact design.
• Supports precise PWM dimming control for adjustable brightness levels in display backlights.
• Operates at a fixed 2.2MHz switching frequency to minimize external passive component size.

LED Driver IC Applications

• White LED backlight drivers for mobile devices
• LCD panel illumination systems
• Portable electronic display modules

LED Driver IC Procurement Notes

Verify the specific suffix designation, as the LF-Z variant is explicitly marked as Not Recommended for New Designs (NRND). Confirm that the LF-P suffix aligns with current manufacturing availability and does not introduce functional deviations compared to standard active listings. Ensure RoHS compliance documentation matches the requested revision level before finalizing procurement orders.

LED Driver IC Selection Notes

Select this component when designing single-string WLED backlight circuits requiring up to 18V output. The 1.33A current capability suits medium-segment displays. Consider the 2.2MHz frequency for EMI management and board space constraints. Verify input voltage stability within the 2.5V to 6V range to ensure proper regulation and dimming performance across the specified industrial temperature range.

LED Driver IC Part Context

This part belongs to the MP3304 series of single-output LED drivers from Monolithic Power Systems. It shares the core boost architecture with variants like the MP3304CDD-LF-Z but may differ in packaging or lifecycle status. The series targets cost-sensitive, space-constrained portable electronics requiring efficient white LED regulation without external MOSFETs.

LED Driver IC Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Designers should consult official MPS documentation for direct pin-compatible alternatives or evaluate the MP3304CDD-LF-Z if lifecycle restrictions permit.
