MP4031GS

Overview

The MP4031GS is a primary-side-controlled offline LED controller featuring active PFC, designed for TRIAC and analog dimmable applications. It operates within an input voltage range of 11 V to 27 V and supports a maximum power dissipation of 1.3 W. The device functions reliably across a temperature range of -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it integrates single-channel output control with a maximum supply current of 2 mA.

Feature Summary

• Integrates active power factor correction for improved efficiency
• Supports TRIAC and analog dimming protocols
• Utilizes primary-side control architecture

Applications

• TRIAC dimmable LED lighting systems
• Analog dimmable LED drivers
• Offline AC-DC LED conversion circuits

Procurement Notes

Verify component authenticity through authorized Monolithic Power Systems distributors or certified partners. Confirm the specific suffix matches the required package and tape/reel specifications. Review the latest datasheet for any design-in updates or compliance changes before finalizing procurement orders.

Selection Notes

Select this component for designs requiring integrated active PFC without secondary-side feedback. Ensure the application utilizes TRIAC or analog dimming signals compatible with the controller's input interface. Verify that the thermal management strategy accommodates the specified 1.3 W power dissipation limit within the operating environment.

Part Context

This part belongs to the MP4031 family of primary-side controlled LED controllers from Monolithic Power Systems. It shares functional similarities with variants like the MP4030 and MP4033 but is distinguished by its specific packaging and pinout configuration suitable for compact LED driver implementations.

Replacement Considerations

Potential substitutes include the MP4030 and MP4033 from the same manufacturer. Verify pin compatibility and dimming signal requirements before substitution.
