MP3304ADD-LF-Z

LED Driver IC Overview

The MP3304ADD-LF-Z is a monolithic boost DC-DC converter designed for driving white LEDs. It operates from an input voltage range of 3 V to 6 V and provides an adjustable output voltage up to 36 V. The device integrates a 1.33 A switch and functions at a fixed switching frequency of 2.2 MHz. It supports true PWM dimming for backlight applications. The component is housed in an 8-QFN (2x3 mm) package with exposed pad and operates within a temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

• Integrates a high-efficiency internal power switch rated for 1.33 A continuous current.
• Supports high-frequency true PWM dimming for precise brightness control without color shift.
• Utilizes a compact 8-QFN surface-mount package to minimize board space requirements.

LED Driver IC Applications

• Mobile phone LCD backlights
• Portable media player displays
• Digital camera flash units

LED Driver IC Procurement Notes

Verify the specific suffix 'ADD' against the manufacturer's latest datasheet to confirm pinout and thermal pad configuration, as variations exist within the MP3304 family. Confirm RoHS compliance status directly with the supplier documentation. Check for end-of-life notifications, as this part may be marked as Not Recommended for New Designs (NRND). Ensure ordering quantities align with standard reel packaging specifications provided by authorized distributors.

LED Driver IC Selection Notes

Select this component when designing LED drivers requiring a single-channel boost topology with integrated switching capability. It is suitable for systems powered by single-cell lithium-ion batteries or similar low-voltage sources. Consider the 2.2 MHz operating frequency for minimizing external passive component sizes compared to lower-frequency alternatives. Verify that the required LED string voltage does not exceed the 36 V maximum output limit.

LED Driver IC Part Context

This device belongs to the MP3304 series of LED lighting driver ICs manufactured by Monolithic Power Systems. The series focuses on high-efficiency step-up conversion for portable electronics. The MP3304ADD-LF-Z specifically denotes the QFN-8 package variant with lead-free and halogen-free construction. It serves as a specialized solution for white LED backlighting in consumer devices where size and efficiency are critical constraints.

LED Driver IC Replacement Considerations

Consult official MPS substitution guides for verified equivalents. Generic replacements may differ in switching frequency, current rating, or package dimensions. Ensure any substitute maintains compatibility with the existing PCB footprint and thermal management design.
