MP1038EY-LF

Lighting, Ballast Controllers Overview

The MP1038EY-LF is a fixed operating frequency inverter controller designed for cold cathode fluorescent lamp (CCFL) applications. It controls four external N-channel power MOSFETs in a full-bridge configuration to drive multi-lamp CCFL arrays. The device operates within a frequency range of 20 kHz to 100 kHz and supports up to 32V output voltage for multi-lamp configurations. Packaged in a 28-SOIC format, it integrates essential control logic for backlight inversion.

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix and package variant against current MPS documentation, as legacy components may have limited availability or updated revisions. Confirm that the 28-SOIC footprint matches your PCB design constraints. Check for end-of-life status or recommended replacement parts if integrating into new designs, as this component may be subject to discontinuation notices.

Lighting, Ballast Controllers Selection Notes

Select this component when a dedicated fixed-frequency controller for full-bridge CCFL inversion is required. Ensure the external MOSFETs can handle the voltage and current demands of the target lamp array. Verify that the system input voltage aligns with the controller's operational limits and that the desired frequency falls within the 20 kHz to 100 kHz range for optimal efficiency and EMI performance.

Lighting, Ballast Controllers Part Context

The MP1038EY-LF belongs to Monolithic Power Systems' portfolio of display driver ICs, specifically targeting CCFL backlight applications. It serves as a core control element in older LCD monitor and laptop display architectures, providing the necessary gate drive signals for the inverter stage. Its integration simplifies the design of high-voltage AC generation for fluorescent lamps.

Lighting, Ballast Controllers Replacement Considerations

Consult MPS datasheets for direct pin-compatible replacements or updated series members. Verify functional equivalence regarding frequency range and bridge configuration before substitution.
