MP4031GS-Z

Overview

The MP4031GS-Z is an offline LED driver IC from Monolithic Power Systems, designed for primary-side controlled applications. It operates within a supply voltage range of 10 V to 27 V and supports analog and Triac dimming capabilities. The device features a single output channel and is housed in an SOIC-8 package. It functions reliably across a temperature range of -40°C to +125°C with a power dissipation rating of 1.3 W.

Feature Summary

• Supports primary-side control topology for simplified circuit design
• Enables brightness adjustment through analog and Triac dimming interfaces
• Integrated protection mechanisms ensure stable operation under varying load conditions

Applications

• Offline LED lighting systems requiring primary-side regulation
• General illumination fixtures compatible with Triac dimmers
• Analog dimmable LED drivers for residential or commercial use

Procurement Notes

Verify the current lifecycle status before procurement as this component may be restricted or discontinued. Confirm that the SOIC-8 package and input voltage specifications align with your specific circuit requirements. Ensure compatibility with existing dimming infrastructure if analog or Triac functionality is required for the target application.

Selection Notes

Select this component for designs requiring primary-side control to reduce external sensing components. Consider the 10 V to 27 V input range when designing the bias supply. Verify thermal management strategies given the 1.3 W power dissipation limit in the SOIC-8 package. Ensure the selected dimming method matches the intended user interface requirements.

Part Context

This part belongs to the MP4031 series of LED lighting drivers manufactured by Monolithic Power Systems. It is categorized under offline LED controllers specifically optimized for primary-side regulation. The series targets cost-sensitive lighting applications where high precision secondary sensing is not mandatory.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter alignment before considering alternative components.
