MP4088GS-P

Overview

The MP4088GS-P is a non-isolated, high power factor correction (PFC) LED driver IC designed for TRIAC dimmable applications. It operates from an input voltage range of 4.1 V to 5 V and supports up to 10 W LEDs in 120VAC systems. The device utilizes a Buck topology and features a SOIC-8-7 package. It functions within a temperature range of -40 °C to +125 °C with a maximum power dissipation of 1.6 W and a maximum supply current of 400 uA.

Feature Summary

• Supports TRIAC dimming functionality for compatibility with standard household switches
• Integrates high power factor correction capabilities for efficient AC line operation
• Provides non-isolated drive architecture suitable for compact lighting designs

Applications

• TRIAC dimmable general illumination fixtures
• Residential LED downlights and bulbs
• Low-power AC-powered LED lamps

Procurement Notes

Verify the specific suffix GS-P against official Monolithic Power Systems documentation to confirm pinout and thermal pad configuration. Ensure the selected variant matches the required SOIC-8-7 package dimensions. Confirm that the component meets all relevant safety standards for the intended market before finalizing procurement orders.

Selection Notes

Select this component for designs requiring integrated PFC and TRIAC dimming in low-voltage control circuits. The Buck topology is appropriate for step-down applications driving LED loads directly. Consider the 400 uA maximum supply current when designing auxiliary power rails for the controller section.

Part Context

This part belongs to the MPS LED Lighting Drivers category, specifically targeting non-isolated solutions. It serves as a specialized controller for AC mains applications where power quality and dimming compatibility are critical design constraints.

Replacement Considerations

Consult official MPS substitution guides for verified alternatives. Generic equivalents may not replicate the specific TRIAC dimming behavior or PFC characteristics required for compliance.
