MP4033GS-P

Overview

The MP4033GS-P is a TRIAC dimmable, primary side control offline LED controller with active PFC. It utilizes a single-stage converter for isolated lighting applications, employing proprietary actual current control via primary side information to regulate LED current precisely. The device operates in critical conduction mode to reduce MOSFET switching losses and features adaptive dimmer type detection with phase-cut dimming control for broad compatibility. It supports PWM input for analog dimming and includes integrated protection mechanisms such as output overvoltage, short circuit, and thermal protection.

Feature Summary

• Primary side control architecture eliminating the need for secondary feedback circuits
• Integrated active power factor correction operating in critical conduction mode
• Adaptive dimmer type detection supporting TRIAC and PWM analog dimming inputs
• Comprehensive protection suite including output overvoltage, short circuit, and thermal shutdown

Applications

• Commercial and industrial isolated LED lighting systems
• TRIAC dimmable AC-DC LED drivers
• Applications requiring high power factor and precise current regulation

Procurement Notes

Verify the specific suffix GS against the official MPS datasheet to confirm package type and temperature range specifications. Ensure design compliance with RoHS3 requirements. Confirm availability status directly with authorized distributors as supply levels fluctuate. Validate that the selected variant matches the required isolation topology and pinout configuration for the target PCB layout.

Selection Notes

Select this component for designs requiring primary side regulation without optocouplers. It is suitable for applications needing active PFC and TRIAC dimming compatibility. Consider the MSOP-10 or SOIC-8 package options based on thermal dissipation needs and board space constraints. Ensure the input voltage range aligns with the target mains supply specifications.

Part Context

The MP4033 series consists of TRIAC dimmable, primary side control offline LED controllers with active PFC. These devices are designed for isolated lighting applications using a single-stage converter. The series offers various package options including SOIC-8, MSOP-10, and SOIC-14 to accommodate different power levels and thermal requirements.

Replacement Considerations

MPS recommends the MP4033GK-Z as a replacement for the discontinued MP4030AGS-P. Verify pinout compatibility and electrical parameters before substitution.
