MPQ1530DQ-AEC1-LF-P

Overview

The MPQ1530DQ-AEC1-LF-P is a triple output step-up plus linear regulator IC designed for TFT bias applications. It features two high-voltage boost converters and one low-noise LDO. Output 1 provides up to 22V at 3.6A, while Output 2 delivers -20V at 20mA. The LDO supplies a stable positive voltage. Operating from a 2.7V to 5.5V supply, it switches at 1.4MHz. Qualified to AEC-Q100 standards, it functions within a junction temperature range of -40°C to +125°C in a QFN package.

Feature Summary

• Triple output architecture combining two boost converters with a dedicated low-noise linear regulator for comprehensive TFT panel biasing requirements.
• High-current capability on the primary boost channel supports demanding display backlight or driver loads efficiently.
• Integrated negative voltage generation simplifies circuit design by eliminating external charge pump components.
• Automotive-grade qualification ensures reliability and performance consistency under rigorous environmental conditions.

Applications

• TFT LCD panel bias power supplies
• Automotive display driver circuits
• In-vehicle infotainment system power management

Procurement Notes

Verify the specific suffix matches the required package and tape/reel configuration. Confirm AEC-Q100 certification status if automotive compliance is mandatory. Check for RoHS3 compliance documentation. Ensure the supplier provides original manufacturer packaging to prevent counterfeit risks. Validate pinout compatibility with existing PCB layouts before finalizing orders.

Selection Notes

Select this component when a single IC solution is needed for generating multiple distinct bias voltages for TFT displays. It is suitable for designs requiring high current on the main boost rail alongside precise negative and low-noise positive rails. Consider thermal dissipation requirements given the 3.6A output capability. Evaluate input voltage ranges against the system battery or supply characteristics.

Part Context

This device belongs to Monolithic Power Systems' portfolio of automotive-qualified power management integrated circuits. It addresses the complexity of powering modern liquid crystal displays by integrating multiple converter topologies into a compact form factor. The series focuses on reducing bill-of-materials count and board space for automotive and industrial display applications.

Replacement Considerations

Direct substitutes include other MPS triple-output TFT bias regulators such as the MPQ1530 variants. Verify equivalent electrical specifications, particularly output currents and voltage ranges. Ensure package dimensions and pin assignments match for drop-in replacement without PCB redesign.
