MP3302DD-LF-P

LED Driver IC Overview

The MP3302DD-LF-P is a boost converter IC designed for driving white LED arrays from a single lithium-ion cell. It operates at a fixed 1.3 MHz switching frequency and delivers up to 1.3 A output current. The device supports an input voltage range of 2.5 V to 6 V and regulates LEDs with a low 200 mV feedback voltage. It features single-wire dimming control, internal power MOSFETs, and protection against overvoltage, overcurrent, and thermal overload. Packaged in an 8-pin QFN (2x3 mm) format.

LED Driver IC Feature Summary

• Single-wire dimming control interface
• Internal power MOSFET drives up to ten series white LEDs
• Low 200 mV feedback voltage for high efficiency
• Integrated protection against open-load overvoltage and thermal stress

LED Driver IC Applications

• Mobile phone backlighting
• Portable electronic device illumination
• Single-cell battery powered LED systems

LED Driver IC Procurement Notes

Verify the suffix 'P' indicates tape-and-reel packaging rather than cut-tape. Confirm the specific package variant matches the 2mm x 3mm QFN-8 footprint. Ensure the order quantity aligns with the manufacturer's standard reel size requirements for this specific part number.

LED Driver IC Selection Notes

Select this component when a compact solution is required for single-cell lithium-ion applications. The fixed 1.3 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. The single-wire dimming capability simplifies control logic integration in space-constrained designs.

LED Driver IC Part Context

This part belongs to the MP3302 family of WLED drivers from Monolithic Power Systems. It shares core electrical specifications with the MP3302DJ-LF variants but differs in packaging and shipping configuration. The DD suffix typically denotes the QFN-8 package style within this product line.

LED Driver IC Replacement Considerations

MP3302DD-LF-Z serves as a direct functional substitute with identical electrical characteristics, differing primarily in packaging format.
