MP3309AGQ-P

LED Driver IC Overview

The MP3309AGQ-P is a synchronous boost WLED driver from Monolithic Power Systems. It operates with an input voltage range of 2.7 V to 5.5 V and supports output voltages up to 35 V. The device delivers an output current of 1.8 A and functions at a switching frequency of 640 kHz. It features analog and PWM dimming capabilities, housed in a QFN-10 package with a power dissipation rating of 2.5 W.

LED Driver IC Feature Summary

• Synchronous boost topology for high efficiency
• Supports both analog and PWM dimming methods
• Integrated internal switch for compact design

LED Driver IC Applications

• White LED backlighting for LCD panels
• Virtual reality display backlighting
• Tablet and notebook screen illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'P' indicates cut-tape or reel packaging options as listed by distributors. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the QFN-10 footprint matches the target PCB layout requirements precisely.

LED Driver IC Selection Notes

Select this component when a single-channel high-current solution is required for portable displays. The 1.8 A output capability suits larger LED arrays compared to lower-current variants. The wide input voltage range accommodates various battery-powered systems without additional regulation stages.

LED Driver IC Part Context

This part belongs to the MP3309A series of LED lighting drivers designed for mobile applications. It shares functional similarities with other MPS WLED drivers but offers specific current and voltage ratings tailored for mid-size panel backlighting needs within consumer electronics.

LED Driver IC Replacement Considerations

Direct substitutes include the MP3309AGQ-Z variant which shares identical electrical specifications. Other MPS models like the MP3314 series offer multi-channel alternatives if additional outputs are required for complex display configurations.
