MP4030AGS

Overview

The MP4030AGS is a TRIAC dimmable, primary side control offline LED controller with active PFC. It supports boost topology and delivers up to 350 mA output current. The device operates from an input voltage of 10 V to 27 V at a switching frequency of 70 kHz. It is housed in an SOIC-8 package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Primary side control eliminates the need for secondary feedback circuits
• Integrated active power factor correction for high efficiency
• Adaptive TRIAC dimming with wide dimming range
• Multiple protection features including overvoltage and thermal shutdown

Applications

• Isolated LED lighting applications using single-stage converters
• TRIAC dimmable general illumination systems
• Smart lighting applications requiring color temperature control

Procurement Notes

Verify the specific suffix AGS against the manufacturer's latest documentation to confirm pinout and packaging details. Check official sources for current production status as this component may be designated as not recommended for new designs. Ensure compatibility with required thermal management solutions given the operating temperature range.

Selection Notes

Select this component for isolated LED driver designs requiring primary side regulation to reduce component count. It is suitable for applications needing integrated PFC and TRIAC dimming capabilities without optocouplers. Evaluate the SOIC-8 package size constraints and thermal dissipation requirements relative to the 350 mA output capability.

Part Context

This part belongs to the MP4030 series of offline LED controllers from Monolithic Power Systems. It is designed to simplify LED lighting system design by integrating power factor correction and dimming control into a single chip. The series targets cost-sensitive, high-performance lighting solutions.

Replacement Considerations

MP4033 is the recommended alternative for new designs.
