MP4030GS-Z

Overview

The MP4030GS-Z is a TRIAC dimmable, primary-side controlled offline LED controller from Monolithic Power Systems. It operates in critical conduction mode with integrated active power factor correction. The device uses an SOIC-8 package and supports an input voltage range of 10 V to 27 V. It features a maximum power dissipation of 1.3 W and functions within a temperature range of -40°C to +125°C. The component provides one output channel with a maximum supply current of 2 mA.

Feature Summary

• Primary-side control architecture eliminates the need for secondary feedback circuits and optocouplers.
• Adaptive TRIAC dimming with phase-cut detection ensures wide dimming ranges and flicker-free operation.
• Integrated VCC charging circuit enables fast startup without noticeable delay.
• Built-in protection mechanisms include overvoltage, short circuit, and overtemperature safeguards.

Applications

• Isolated LED lighting applications using single-stage converters
• TRIAC dimmable general illumination systems
• Smart lighting solutions requiring high power factor

Procurement Notes

Verify the NRND status before procurement, as this component is not recommended for new designs. Confirm that the SOIC-8 package and specific suffix align with existing schematic requirements. Check for moisture sensitivity handling during storage. Ensure replacement strategies are evaluated due to potential obsolescence.

Selection Notes

Select this controller for isolated flyback topologies requiring primary-side regulation. It is suitable for designs needing high power factor and TRIAC dimming compatibility. Consider the MP4033 as a recommended alternative for new projects. Evaluate thermal performance given the 1.3 W power dissipation limit in the SOIC-8 package.

Part Context

This part belongs to the MP4030A series of offline LED controllers. It is designed to simplify LED driver design by removing secondary feedback components. The series focuses on cost-effective, high-performance lighting solutions with integrated power factor correction and robust protection features for commercial and residential use.

Replacement Considerations

Public documentation recommends the MP4033 as the alternative for new designs. Verify pinout and electrical parameter compatibility before substitution. The MP4030 continues production for existing customers but may face long lead times.
