MP3399EF-LF

Overview

The MP3399EF-LF-Z is a high-voltage boost LED driver IC designed for white LED control. It features 12 output channels and operates with an input voltage range of 5 V to 28 V. The device utilizes a boost topology with a fixed switching frequency of 570 kHz. It is housed in a TSSOP-28 package and supports surface mount installation. The component functions within a temperature range of -40°C to +125°C, with a maximum power dissipation of 3.9 W.

Feature Summary

Supports up to 12 independent LED strings for uniform current distribution
Integrated high-voltage boost converter architecture
Operates across a wide input voltage range suitable for various power sources

Applications

White LED lighting systems
High-voltage LED string drivers
General LED illumination applications

Procurement Notes

Verify the specific suffix (e.g., LF-Z) against official Monolithic Power Systems documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the ordering part number matches the exact package variant required for the design. Cross-reference the manufacturer's latest datasheet to validate RoHS compliance details and moisture sensitivity levels prior to procurement.

Selection Notes

Select this component when designing circuits requiring multiple parallel LED strings driven by a single controller. The 570 kHz switching frequency offers a balance between efficiency and external component size. Consider the 28 V maximum input limit and 3.9 W power dissipation capability when determining thermal management requirements for the TSSOP-28 package in the target application environment.

Part Context

This part belongs to the MP3399 series of LED lighting drivers from Monolithic Power Systems. It is categorized under LED Lighting Drivers and Driver ICs. The device is specifically engineered for white LED applications, distinguishing it from general-purpose switching regulators or buck converters within the manufacturer's broader portfolio.

Replacement Considerations

Consult the official MPS product selection guide for direct substitutes within the MP3399 family. Verify pin compatibility and electrical specifications before replacing with other LED driver ICs.
