MP4033GSE-P

Overview

The MP4033GSE-P is a TRIAC-dimmable, primary side-control offline LED lighting controller with active PFC. It operates in MSOP-10 packages and supports flyback topology for isolated applications. The device accepts an input voltage range of 11 V to 27 V on the power pin. It features one output channel and supports analog, PWM, and TRIAC dimming methods. The component functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Primary-side control eliminates the need for secondary-side feedback circuits
• Adaptive dimmer type detection ensures compatibility with TRIAC phase-cut dimmers
• Integrated active PFC improves power factor efficiency
• Supports color temperature and brightness control via PWM input

Applications

• Solid-state lighting up to 50W
• Industrial and commercial lighting systems
• Residential lighting fixtures

Procurement Notes

Verify the specific suffix 'GSE' against official Monolithic Power Systems documentation to confirm package dimensions and thermal characteristics. Ensure design compliance with RoHS3 standards as indicated for the series. Cross-reference the exact part number with manufacturer datasheets to validate availability status and recommended design-in alternatives if necessary.

Selection Notes

Select this component for isolated AC-DC LED driver designs requiring high power factor correction without optocouplers. The primary-side regulation simplifies the bill of materials. Consider the MSOP-10 footprint constraints and thermal dissipation requirements when designing the PCB layout for continuous operation at elevated temperatures.

Part Context

This IC belongs to the MP4033 family of offline LED controllers designed for single-stage converters. It replaces older generations like the MP4030 by offering enhanced dimming compatibility and integrated active PFC capabilities. The series targets cost-sensitive yet high-performance lighting applications where isolation and precise current regulation are mandatory.

Replacement Considerations

MP4033GK-Z and MP4033GS-Z are confirmed substitutes within the same product family.
