MPQ1530DQ-AEC1-LF-Z

Overview

The MPQ1530DQ-AEC1-LF-Z is an automotive-grade, triple-output step-up converter designed for TFT LCD bias applications. It operates with an input voltage range of 2.7 V to 5.5 V and provides three adjustable output voltages from 2.7 V to 22 V. The device delivers a total output current of 2.8 A and features a fixed switching frequency of 1.4 MHz. It includes integrated soft-start, overcurrent protection, and thermal shutdown. The component is housed in a compact 16-pin QFN package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Triple-output boost topology optimized for driving TFT LCD panel bias circuits
• Automotive qualification compliant with AEC-Q100 standards for reliability
• Integrated protection mechanisms including overcurrent limiting and thermal shutdown

Applications

• TFT LCD bias power supplies in automotive infotainment systems
• Display driver power stages in vehicle instrument clusters
• High-voltage generation for automotive display backlighting circuits

Procurement Notes

Verify the specific suffix 'AEC1' confirms automotive grade status against the manufacturer's official datasheet. Confirm the package marking matches the 16-QFN specification. Ensure design-in compliance with AEC-Q100 requirements if used in safety-critical automotive environments. Check for any recent lifecycle notices regarding obsolescence or pin-compatible alternatives.

Selection Notes

Select this component when designing power solutions for automotive displays requiring multiple independent bias rails from a single low-voltage source. It is suitable for systems needing high efficiency at light loads due to the fixed frequency operation. Consider the 1.4 MHz switching frequency for balancing EMI performance and external component size. Verify that the total load current does not exceed the 2.8 A aggregate limit across all three outputs.

Part Context

This part belongs to the MP1530 family of triple-output step-up converters. The MPQ variant specifically denotes automotive-grade qualification, distinguishing it from the standard commercial MP1530 series. It serves as a specialized power management IC for display applications within the Monolithic Power Systems portfolio.

Replacement Considerations

The MP1530DM-LF-Z is a commercial-grade equivalent with identical electrical specifications but lacks automotive qualification. Verify if the application requires AEC-Q100 certification before substituting.
