MP4021GS-A

Overview

The MP4021GS-A is an AC/DC offline switcher designed for LED lighting applications. It operates within a supply voltage range of 10.3 V to 23 V and delivers a single output current of 1 A. The device utilizes a flyback topology without internal switches or dimming capabilities. It is housed in an 8-SOIC package and supports surface-mount installation. The component functions across a temperature range of -40 °C to +125 °C TJ.

Feature Summary

• Integrated AC/DC offline switching controller for non-isolated LED driver topologies
• Flyback converter architecture optimized for constant current LED loads
• Operates with external power MOSFETs in a compact SOIC-8 package

Applications

• Offline LED lighting fixtures
• AC-powered general illumination systems
• Non-dimmable LED driver circuits

Procurement Notes

Verify the specific suffix (A-P or A-Z) against the required packaging format, as both variants exist. Confirm that the NRND status aligns with long-term production requirements. Ensure the 8-SOIC footprint matches the PCB layout constraints. Check moisture sensitivity level handling procedures if storage time has exceeded limits.

Selection Notes

Select this component for simple, cost-effective AC/DC LED drivers requiring a single output channel. It is suitable for designs where integrated dimming is not required. Consider the NRND status when planning new product introductions; alternative models like MP4026 or MP4027 are recommended for new designs. Verify input voltage compatibility with the 10.3 V to 23 V operating window.

Part Context

This part belongs to the MP4021 series from Monolithic Power Systems, focusing on LED lighting driver ICs. It serves as a foundational controller for basic AC/DC conversion tasks. The series targets manufacturers seeking reliable, low-component-count solutions for standard lighting applications without complex control features.

Replacement Considerations

Official recommendations suggest MP4026 and MP4027 for new designs due to the NRND status of the MP4021 series. Direct pin-to-pin replacements are not explicitly documented in the provided source material.
