MPQ7230GLE-AEC1-P

Overview

The MPQ7230GLE-AEC1-P is an AEC-Q100 qualified infrared LED driver IC designed for automotive applications. It supports Buck and Buck-boost topologies with a single output channel. The device operates within a 6 V to 42 V input voltage range and delivers up to 1.2 A in Buck-boost mode or 3 A in Buck mode. It features a fixed switching frequency of 410 kHz and PWM dimming capability. The component is housed in a 19-QFN (3x4) package, rated for junction temperatures from -40°C to +150°C, with a maximum power dissipation of 3.9 W.

Feature Summary

• Integrated synchronous Buck and Buck-boost topology for flexible LED drive configurations
• AEC-Q100 qualification ensuring reliability for automotive infrared LED applications
• Supports PWM dimming control for precise brightness management
• Wide input voltage range accommodating various automotive power supply conditions

Applications

• Driver Monitoring Systems
• Automotive Infrared LED Lighting
• Interior Ambient Lighting

Procurement Notes

Verify the specific suffix 'P' indicates reel packaging configuration when sourcing. Confirm that the AEC-Q100 grade is required for the target automotive application. Ensure the 19-QFN footprint matches the PCB design constraints. Check for RoHS3 compliance requirements against project specifications. Validate the 410 kHz switching frequency compatibility with system EMI filters.

Selection Notes

Select this component for designs requiring high current drive for infrared LEDs in automotive environments. The Buck-boost capability allows operation across wide input voltage fluctuations typical in vehicle electrical systems. Consider the thermal performance given the 3.9 W power dissipation limit in the QFN package. Compare against non-automotive grades if cost sensitivity outweighs certification needs. Evaluate PCB space availability for the 19-pin QFN outline.
