MPQ24833-BGN-AEC1-P

Overview

The MPQ24833-BGN-AEC1-P is an automotive-grade LED driver IC from Monolithic Power Systems, designed for industrial and automotive applications. It features a wide input voltage range of 4.5V to 55V and supports a maximum output current of 3A. The device utilizes Buck and Buck-Boost topologies with a fixed switching frequency of 420kHz. It is housed in an SOIC-8 package and holds AEC-Q100 qualification. The operational temperature range spans from -40°C to +125°C, ensuring reliability in demanding environments.

Feature Summary

• Supports unique boost/buck operating modes (buck-boost mode) for flexible LED string configurations
• Integrates analog and PWM dimming functions on a single control pin
• Includes comprehensive protection mechanisms such as over-temperature shutdown, cycle-by-cycle overcurrent protection, open-loop protection, and short-circuit protection

Applications

• Automotive exterior lighting systems
• Industrial LED illumination arrays
• High-voltage LED backlighting solutions

Procurement Notes

Verify the specific suffix 'BGN' against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad configuration. Ensure that the AEC-Q100 qualification status aligns with your system's automotive grade requirements. Cross-reference the SOIC-8 EP package dimensions with your PCB layout guidelines to guarantee proper soldering and thermal dissipation performance during integration.

Selection Notes

Select this component when a wide input voltage range up to 55V is required alongside high current capability of 3A. It is suitable for designs needing both buck and buck-boost functionalities within a single channel. Consider the 420kHz switching frequency for balancing efficiency and external component size. Verify that the SOIC-8 package fits the available board space and thermal management strategy.
