MP4021GS-A-Z

Overview

The MP4021GS-A-Z is an AC/DC offline switcher IC designed for flyback converter topologies. It operates within a supply voltage range of 10.3 V to 23 V and features a single output channel. The device is housed in an 8-SOIC package with a width of 3.90 mm. It supports a junction temperature range from -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Integrated AC/DC offline switching controller for flyback applications
• Single-channel output configuration for LED driver systems
• Operates without internal power switches

Applications

• LED lighting drivers
• Offline AC/DC power supplies
• Flyback converter circuits

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's current datasheet to confirm pinout and electrical characteristics, as suffixes often denote revisions or specific binning. Confirm that the component status is acceptable for new designs, as some MPS parts may be marked as Not Recommended for New Designs (NRND). Ensure the 8-SOIC footprint matches the PCB layout requirements.

Selection Notes

Select this component for applications requiring a simple offline flyback solution without integrated high-voltage MOSFETs. The wide operating voltage range suits various AC input conditions. Consider the thermal performance within the 8-SOIC package when designing for high ambient temperatures up to 125°C junction limit.

Part Context

This part belongs to the Monolithic Power Systems MP4021 series, which focuses on offline LED driving solutions. The series provides cost-effective alternatives for non-isolated or isolated flyback designs where external switching elements are preferred or required by the system architecture.

Replacement Considerations

Check for direct pin-to-pin replacements within the MP4021 family or other MPS offline controllers. Verify compatibility with existing transformer designs and control loop compensation when substituting.
