MP4050AGS

Overview

The MP4050AGS-Z is a non-isolated, high-brightness LED driver IC from Monolithic Power Systems. It utilizes a Buck topology with a single output channel housed in an SOIC-8 package. The device operates within an input voltage range of 4.1 V to 5 V and features a fixed switching frequency of 22 kHz. Maximum power dissipation is rated at 1.3 W, with a maximum supply current of 6.1 mA. The component supports surface mount installation and is designed for driving high-brightness LEDs.

Feature Summary

• Non-isolated Buck topology design for efficient LED driving
• Integrated internal switch for compact implementation
• Fixed 22 kHz switching frequency operation

Applications

• High brightness LED lighting systems
• General illumination applications
• Low voltage LED driver circuits

Procurement Notes

Verify the specific suffix (e.g., Z or P) when ordering, as it determines packaging quantity and thermal characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the selected variant matches the required input voltage range and thermal management capabilities for the target application environment.

Selection Notes

Select the MP4050AGS-Z for reel-based production requiring standard packaging. Choose the MP4050AGS-P variant if enhanced thermal features are necessary or if cut-tape quantities are preferred. Both variants share the same core electrical specifications but differ in physical handling and thermal performance attributes defined by their respective suffixes.

Part Context

This component belongs to the MP4050 series of LED lighting drivers. It serves as a specialized integrated circuit for managing high-brightness LED loads in non-isolated configurations. The series provides solutions for low-voltage applications where space constraints and efficiency are critical design factors.

Replacement Considerations

MP4050AGJ-Z is listed as a parameter-equivalent alternative in TSOT-23-5 packaging.
