Overview
The MP4021AGS-Z is an AC/DC LED driver IC from Monolithic Power Systems, designed for offline flyback topologies. It operates within a supply voltage range of 10.3 V to 23 V and delivers a single output channel with a maximum current of 1 A. The component is housed in an 8-SOIC package and supports surface-mount installation. It functions across a wide temperature range from -40°C to +125°C TJ. This device is classified as not recommended for new designs.
Feature Summary
- Supports AC/DC offline flyback topology for LED lighting applications
- Provides constant current regulation for single-channel LED strings
- Operates without internal power switches
Applications
- LED street illumination systems
- General-purpose LED lighting drivers
- Offline AC/DC power supplies for lighting
Procurement Notes
Verify the obsolete status before procurement, as this part is marked Not Recommended for New Designs (NRND). Confirm availability through authorized distributors or surplus channels. Ensure compatibility with existing PCB footprints if replacing older units. Check for alternative recommendations such as the MP4026 or MP4027 series for new projects. Validate RoHS compliance and moisture sensitivity levels prior to assembly.
Selection Notes
Select this component only for maintenance or legacy system upgrades where the original design specifies the MP4021A family. Evaluate the 1 A output current capability against the target LED string requirements. Consider the 8-SOIC package constraints for thermal management. Review the input voltage range of 10.3 V to 23 V to ensure it matches the controller's operating conditions. Assess the lack of dimming features if variable brightness control is required.
Part Context
This IC belongs to the MP4021 series of LED drivers manufactured by Monolithic Power Systems. It is specifically engineered for non-isolated or isolated flyback converters driving white LEDs. The series is positioned for cost-effective lighting solutions, though newer generations like the MP4026 offer enhanced features for modern designs.
Replacement Considerations
Officially recommended replacements for new designs include the MP4026 and MP4027 models. Verify pinout compatibility and electrical specifications when substituting these parts into existing circuits.
