MP4050AGS-P

Overview

The MP4050AGS-P is a non-isolated, high-brightness LED driver IC manufactured by Monolithic Power Systems. It utilizes a buck topology to drive LEDs from a single supply voltage ranging from 4.1 V to 5 V. The device features an output current of 5 mA and operates at a switching frequency of 33 kHz. Packaged in an SOIC-8 format, it supports surface-mount installation and functions within a temperature range of -40°C to +125°C. Key electrical specifications include a maximum power dissipation of 1.3 W and a maximum supply current of 425 uA.

Feature Summary

• Integrated thermal protection mechanisms for enhanced operational safety
• Designed specifically for driving high-brightness LEDs with constant current regulation
• Supports pulse-width modulation (PWM) dimming capabilities

Applications

• High-brightness LED lighting systems
• Portable electronic devices requiring efficient LED drivers
• General illumination applications using low-voltage DC supplies

Procurement Notes

Verify the specific suffix 'GS' confirms the SOIC-8 package variant when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage constraints between 4.1 V and 5 V are strictly maintained during system design to prevent malfunction or damage to the component.

Selection Notes

Select this component for designs requiring a compact, single-output buck converter solution for low-current LED applications. The SOIC-8 package offers a balance of thermal performance and board space efficiency compared to smaller packages. Consider the 5 mA output limit when determining the number of LEDs per string, as higher currents require different driver architectures.

Part Context

This part belongs to the MP4050 series of LED drivers from Monolithic Power Systems. The series focuses on simple, cost-effective solutions for low-power LED applications. The AGS suffix denotes the specific pinout and package type, distinguishing it from other variants like the AGJ which uses a TSOT-23-5 package. This family targets consumer electronics and portable lighting markets.

Replacement Considerations

The MP4050AGJ-P serves as a functional alternative with identical electrical characteristics but utilizes a TSOT-23-5 package instead of SOIC-8. Designers must verify footprint compatibility and thermal management requirements when substituting between these package types.
