Overview
The MP3394SGF is a Monolithic Power Systems LED lighting driver IC featuring four output channels with a maximum current of 180 mA per channel. It utilizes a boost topology and operates within an input voltage range of 5 V to 28 V. The device supports a fixed switching frequency of 570 kHz and is housed in a TSSOP-EP-16 package. It functions as a white LED driver designed for applications requiring precise current regulation.
Feature Summary
- Integrates four internal current sources to drive white LED strings with high current matching accuracy.
- Supports PWM dimming control via external signals or DC input for flexible brightness adjustment.
- Includes comprehensive protection mechanisms such as open LED detection, short circuit protection, and overvoltage protection.
Applications
- Backlighting for large LCD panels
- White LED arrays in 2D/3D monitors
- Television display backlight systems
Procurement Notes
Verify the specific suffix against official MPS documentation to confirm package type and environmental compliance. Confirm availability status as some variants may be discontinued or restricted. Ensure the selected part matches the required thermal performance and pinout configuration for the target PCB layout.
Selection Notes
Select this component for designs requiring four independent LED channels with integrated boost conversion. Consider the TSSOP-EP-16 package for thermal management needs. Evaluate the fixed 570 kHz frequency against external magnetic component requirements. Verify compatibility with system dimming control interfaces before finalizing the design.
Part Context
This device belongs to the MP3394S series of WLED drivers from Monolithic Power Systems. The series is engineered for monitor and TV backlight applications, offering scalable solutions through cascading capabilities. It represents a specialized solution for high-density LED driving in consumer electronics displays.
Replacement Considerations
Official substitutes include MP3394SGF-Z and MP3394SGS-P. Verify pin compatibility and electrical specifications before substitution. Consult MPS documentation for any functional differences between suffixes.
