MP4050AGJ-Z

Overview

The MP4050AGJ-Z is a non-isolated, high-brightness LED driver IC from Monolithic Power Systems. It utilizes a buck topology with a single output channel capable of delivering up to 115 mA. The device operates within an input voltage range of 4.1 V to 5 V and features a fixed switching frequency of 22 kHz. Designed for surface-mount installation in TSOT-23-5 packages, it supports a wide operating temperature range from -40°C to +125°C TJ. The component integrates internal power switches and is compliant with RoHS standards.

Feature Summary

Integrates a buck converter topology for efficient step-down voltage regulation suitable for LED applications.
Features a compact TSOT-23-5 package design optimized for space-constrained surface-mount PCB layouts.
Supports extended thermal operation capabilities across industrial temperature ranges.

Applications

High brightness LED lighting systems
General illumination circuits
Offline switch mode LED drivers

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical specifications. Confirm current lifecycle status as some sources indicate restricted new design usage. Ensure environmental compliance declarations match project requirements prior to integration into final assemblies.

Selection Notes

Select this component for applications requiring low-frequency operation at 22 kHz to minimize electromagnetic interference. The narrow input voltage window necessitates stable supply rails. Evaluate thermal dissipation requirements given the small package size and ensure adequate copper area for heat spreading during high-current operation.

Part Context

This part belongs to the MP4050 series of LED drivers designed by Monolithic Power Systems. It serves as a specialized solution for driving high-brightness LEDs without isolation barriers. The series focuses on cost-effective and compact implementations for general lighting markets where simple control architectures are preferred.
