MPQ24833-BGN-AEC1-Z

Overview

The MPQ24833-BGN-AEC1-Z is an automotive-grade white LED driver IC manufactured by Monolithic Power Systems. It supports a wide input voltage range from 4.5 V to 55 V and delivers up to 3 A of output current. The device integrates boost, buck, and buck-boost topologies within a single SOIC-8 package. It operates at a fixed switching frequency of 200 kHz and includes analog and PWM dimming capabilities. Designed for high reliability, it meets AEC-Q100 standards with a junction temperature range of -40°C to +125°C.

Feature Summary

• Supports versatile boost, buck, and buck-boost operating modes for flexible LED string configurations.
• Integrates combined analog and PWM dimming control on a single pin for simplified interface.
• Includes comprehensive protection features such as over-temperature shutdown, open-loop, and short-circuit protection.

Applications

• Automotive exterior lighting systems
• Automotive interior ambient lighting
• High-voltage LED backlighting arrays

Procurement Notes

Verify the specific suffix 'AEC1' confirms AEC-Q100 automotive qualification status against the official datasheet. Confirm the package type matches the required SOIC-8 footprint. Check for any obsolescence notices or recommended alternative part numbers provided by the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring a single IC to handle varying input-to-output voltage relationships in automotive environments. Ensure the thermal design accommodates the power dissipation limits specified in the datasheet. Verify that the external passive components support the 200 kHz switching frequency and the required output current levels.

Part Context

This part belongs to the MP24833 family of LED drivers, specifically tailored for automotive applications. It shares core functionality with the commercial MP24833 but adheres to stricter automotive reliability standards. The series is designed to simplify designs by combining multiple converter topologies into one controller.

Replacement Considerations

Consult the manufacturer's documentation for officially recommended alternatives if this part is no longer suitable for new designs. Cross-reference electrical parameters and pinouts carefully when considering substitute components from other manufacturers.
