MP3304BDD-LF-Z

LED Driver IC Overview

The MP3304BDD-LF-Z is a monolithic DC-DC step-up (boost) converter designed for white LED backlighting applications. It integrates an internal power switch capable of delivering up to 1.33A. The device operates within an input voltage range of 2.5V to 6V and supports PWM dimming control. It functions at a fixed switching frequency of 2.2MHz, enabling the use of small external components. The IC is housed in an 8-pin QFN package with dimensions of 2x3mm.

LED Driver IC Feature Summary

• Integrates a high-efficiency internal power switch for compact design
• Supports precise pulse-width modulation (PWM) dimming control
• Utilizes a fixed high-frequency operation to minimize passive component size

LED Driver IC Applications

• White LED backlighting for mobile devices
• Portable electronic equipment illumination
• General-purpose boost conversion for low-voltage systems

LED Driver IC Procurement Notes

Verify the specific suffix 'BDD' against the manufacturer's official datasheet to confirm pinout and electrical characteristics, as variations exist within the MP3304 family. Confirm RoHS compliance status directly with the supplier documentation. Ensure the source document explicitly identifies this part number as the intended component for your design requirements.

LED Driver IC Selection Notes

Select this component when a single-channel boost driver is required for white LEDs with input voltages between 2.5V and 6V. The 2.2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the 8-QFN package constraints for thermal management and PCB layout space availability in portable designs.
