MP4068GS-P

Overview

The MP4068GS-P is a non-isolated, TRIAC dimmable PFC LED driver IC designed for 120VAC applications with power ratings up to 10W. It utilizes a Buck topology and operates within an input voltage range of 4.1 V to 5 V. The device features a single output channel and is housed in an SOIC-8-7 package. It supports surface mount installation and functions reliably across a temperature range of -40°C to +125°C. Key electrical specifications include a maximum power dissipation of 1.6 W and a maximum supply current of 400 uA.

Feature Summary

• Integrates active Power Factor Correction (PFC) functionality
• Supports TRIAC dimming compatibility
• Designed for non-isolated LED driving topologies

Applications

• 120VAC LED lighting systems
• Low-power LED drivers up to 10W
• TRIAC dimmable lighting fixtures

Procurement Notes

Verify the specific suffix 'P' against official Monolithic Power Systems documentation to confirm packaging configuration and availability status. Ensure design compliance with humidity sensitivity requirements and thermal management limits specified in the datasheet before procurement.

Selection Notes

Select this component for non-isolated designs requiring integrated PFC and TRIAC dimming capabilities. Confirm that the Buck topology aligns with the target LED string voltage and current requirements. Validate that the SOIC-8-7 package fits the PCB layout constraints and thermal dissipation needs.

Part Context

This part belongs to the MPS LED Lighting Drivers category, specifically under Driver ICs. It is distinct from other series like MP4031 or MP4050 by its specific integration of PFC and TRIAC dimming for low-voltage auxiliary or direct drive applications.

Replacement Considerations

MPS recommends the MP4050A as a replacement for the older MP4050 series. No direct substitute is explicitly confirmed for the MP4068GS-P in available public data.
