MP4068GN-Z

Overview

The MP4068GN-Z is a non-isolated TRIAC dimmable PFC LED driver IC from Monolithic Power Systems. It integrates power factor correction and LED driving functions using Buck and Buck-Boost topologies. The device operates with an input voltage range of 4.1 V to 5 V and features a fixed switching frequency of 22 kHz. It supports brightness control and dimming capabilities, housed in an SOIC-EP-8 package with a maximum power dissipation of 2.6 W.

Feature Summary

• Integrates non-isolated TRIAC dimmable PFC and LED driver functions
• Supports brightness control and dimming applications
• Utilizes Buck and Buck-Boost converter topologies

Applications

• LED lighting systems requiring TRIAC dimming compatibility
• Non-isolated power factor correction circuits
• Brightness controlled LED driver designs

Procurement Notes

Verify the specific suffix GN-Z against official Monolithic Power Systems documentation to confirm pinout and thermal pad configuration. Ensure design compliance with humidity sensitivity levels indicated in the datasheet. Confirm that the SOIC-EP-8 package requirements align with manufacturing capabilities before finalizing procurement orders.

Selection Notes

Select this component for applications requiring integrated PFC and LED driving in a non-isolated topology. The 22 kHz operating frequency and 4.1 V to 5 V input range define the electrical boundaries. Consider the 2.6 W power dissipation limit when designing thermal management solutions for the SOIC-EP-8 package.

Part Context

The MP4068GN-Z belongs to the MP4068 series of LED lighting driver ICs manufactured by Monolithic Power Systems. This series focuses on providing efficient power factor correction and LED drive solutions for commercial and industrial lighting applications without requiring isolation transformers.

Replacement Considerations
