MP4050GJ-Z

Overview

The MP4050GJ-Z is a non-isolated, high-brightness LED driver IC from Monolithic Power Systems. It utilizes a buck topology and features an integrated MOSFET. The device supports an input voltage range of 85 V to 265 V and delivers an output current of 115 mA. Operating at a fixed frequency of 22 kHz, it is housed in a TSOT-23-5 package. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a power MOSFET for compact design
• Supports AC/DC offline switching applications
• Designed for high-brightness LED driving

Applications

• General lighting systems
• Commercial illumination fixtures

Procurement Notes

Verify the specific suffix 'Z' against official datasheets to confirm RoHS compliance status. Confirm the package designation matches the required TSOT-23-5 footprint. Check the lifecycle status as some sources indicate this part may be recommended against new designs (NRND). Ensure compatibility with the intended thermal management requirements for the specified operating temperature range.

Selection Notes

Select this component for non-isolated buck converter LED topologies requiring wide input voltage ranges. The integrated MOSFET simplifies the external circuit design compared to discrete solutions. Verify that the 115 mA output current aligns with the target LED string configuration. Consider the 22 kHz switching frequency regarding electromagnetic interference constraints in the final application environment.

Part Context

This part belongs to the MP4050 series of LED drivers from Monolithic Power Systems. The series includes variants such as the MP4050AGS-Z which operates at lower voltages (4.1 V to 5 V) and uses an SOIC-8 package. The GJ-Z suffix specifically denotes the TSOT-23-5 package variant designed for higher voltage offline applications.

Replacement Considerations

MP4050AGJ-P is listed as a parameter equivalent alternative.
