Overview
The MP3351DQ-LF-Z is a Xenon flash charger IC from Monolithic Power Systems, designed for display driver applications. It operates on a supply voltage range of 3 V to 6 V and delivers a maximum output current of 2 A. The device functions at a switching frequency of 400 kHz with a quiescent current of 2.5 mA. It supports an output voltage up to 60 V and is housed in a QFN-16 package. The component is rated for operation between -40°C and +85°C.
Feature Summary
- Integrated charge management circuitry specifically engineered for xenon flash lamp applications
- Capable of delivering high peak output currents required for flash charging cycles
- Includes internal switching elements to simplify external component count
Applications
- Xenon flash lamp charging systems
- Camera module power management
- Display driver controller interfaces
Procurement Notes
Verify the NRND status before integration, as this designation indicates the component is not recommended for new designs. Confirm that the QFN-16 package dimensions align with your PCB layout constraints. Ensure the 3 V to 6 V input range matches your system's power supply rails. Check for updated lifecycle notices from the manufacturer regarding end-of-life timelines.
Selection Notes
Select this part when a dedicated xenon flash charger is required within a compact form factor. The 2 A output capability suits standard xenon tube requirements. The 400 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify thermal performance in the QFN-16 package under continuous load conditions.
Part Context
This component belongs to the MP3351 series of display drivers and controllers. It serves as a specialized power management solution for integrating xenon flash functionality into portable electronic devices. The design focuses on efficiency and size reduction for mobile camera modules.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer for current alternative recommendations due to the NRND status.
