Overview
The MP3394SGS-Z is a four-channel boost white LED driver IC manufactured by Monolithic Power Systems. It operates with an input voltage range of 5V to 28V and provides up to 180mA output current per channel. The device utilizes a fixed-frequency architecture with a switching frequency of 670kHz. It features a 16-SOIC surface-mount package and supports PWM dimming control. The component includes integrated protection mechanisms such as over-voltage, over-temperature, and open/short circuit detection for reliable operation in backlight applications.
Feature Summary
- Four independent current sources for precise LED string regulation
- Integrated boost topology controller for external MOSFET drive
- Supports PWM and DC input burst mode dimming functions
- Comprehensive protection against over-voltage, over-temperature, and faults
Applications
- Backlight drivers for LCD panels
- White LED arrays in monitors
- LED lighting systems requiring multi-channel control
Procurement Notes
Verify the specific suffix 'Z' indicates lead-free compliance and RoHS status. Confirm the package type matches the design requirements, as variants exist in different footprints. Check the manufacturer's latest documentation for any updates regarding the recommended alternative part numbers, as this series may be transitioning to newer designs.
Selection Notes
Select this component when a four-channel boost driver is required for WLED backlighting. Ensure the application input voltage falls within the 5V to 28V range. Consider the 180mA per channel limit and the 670kHz switching frequency for thermal and EMI management. Verify compatibility with the system's dimming interface requirements.
Part Context
This part belongs to the MP3394 series of LED lighting drivers from Monolithic Power Systems. The series is designed for driving white LED arrays in display applications. The MP3394SGS-Z specifically denotes the SOIC-16 package variant within this family, offering multi-channel current balancing capabilities.
Replacement Considerations
The manufacturer lists MP3394S as the alternative for new designs. Evaluate the MP3394S for pinout compatibility and updated specifications if replacing this component in new projects.
