Overview
The MPQ2483DQ-AEC1-LF-Z is a single-channel Buck-Boost LED driver IC from Monolithic Power Systems, designed for automotive applications. It operates with an input voltage range of 4.5 V to 55 V and delivers up to 2.5 A output current. The device features a fixed switching frequency of 250 kHz and supports both analog and PWM dimming methods. Packaged in a QFN-10 format, it is qualified under AEC-Q101 standards for operation between -40°C and +125°C.
Feature Summary
- Supports Buck-Boost topology for flexible LED string configurations
- Enables precise brightness control via analog and PWM dimming inputs
- Automotive-grade qualification ensures reliability in harsh environments
Applications
- Automotive exterior lighting systems
- Headlamp modules requiring wide input voltage tolerance
- LED accent lighting in vehicle interiors
Procurement Notes
Verify the Not For New Designs (NRND) status before initiating any new product development projects. Confirm that the QFN-10 package dimensions align with your PCB layout constraints. Ensure supply chain readiness for long production cycles associated with this specific component variant.
Selection Notes
Select this component when designing circuits requiring high input voltage tolerance up to 55 V. It is suitable for applications needing constant current regulation with integrated dimming capabilities. Consider the thermal performance within the QFN-10 package for your specific power dissipation requirements.
Part Context
This part belongs to the MPQ2483 series of automotive-grade LED drivers. It shares functional similarities with other MPS Buck-Boost controllers but is distinct due to its specific 2.5 A current rating and 250 kHz fixed frequency operation tailored for robust automotive lighting solutions.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific NRND component. Designers should evaluate alternative MPS LED drivers with compatible voltage and current ratings if redesigning.
