- Provides active PFC for improved power efficiency
Applications
- LED lighting drivers
- Virtual reality LCD panel backlighting
- Display backlights
Procurement Notes
Verify the specific suffix and pin configuration against the official datasheet before integration. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the selected package variant matches the PCB footprint requirements. Validate thermal management solutions for the specified power dissipation limits during operation.
Selection Notes
Select this component for applications requiring a compact, primary-side controlled solution without external gate drive components. The integrated MOSFET reduces bill of materials count. Consider the operating temperature range and power dissipation characteristics when designing the thermal profile for the enclosure.
Part Context
This part belongs to the Monolithic Power Systems LED driver family, specifically designed for offline AC-DC conversion. It serves as a cost-effective alternative to discrete solutions by combining control logic and power switching into a single IC. The series targets general illumination and display backlight markets.
Replacement Considerations
Check for direct substitutes such as the MP4031GS-P or MP4033GK-P from the same manufacturer, ensuring package compatibility and electrical parameter alignment.
