MPQ4431GL-AEC1-Z is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists Monolithic Power Systems Inc.. Its product description is IC REG 1A 16QFN. Review the specifications below when checking this part for your BOM.
The MPQ4431GL-AEC1-Z is an automotive-grade synchronous step-down converter from Monolithic Power Systems. It integrates high-side and low-side power MOSFETs to deliver a continuous output current of 1A. The device supports a wide input voltage range of 3.3V to 36V and features a programmable switching frequency between 350kHz and 2.5MHz. It operates with a quiescent current of 10uA in sleep mode and includes AAM mode for light-load efficiency. Qualified under AEC-Q100 Grade-1, it functions within a temperature range of -40°C to +125°C and is housed in a QFN-16 (3mmx4mm) package.
Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status as per manufacturer standards. Confirm the 'AEC1' designation aligns with required AEC-Q100 Grade-1 reliability specifications for your target application. Ensure the QFN-16 package dimensions match your PCB footprint requirements. Cross-reference the datasheet revision date to confirm compatibility with your design parameters.
Select this component when a 1A output current is sufficient for the load requirements. It is suitable for applications requiring a wide input voltage range up to 36V. Consider this part if low static current is critical for battery life. Verify that the required switching frequency falls within the 350kHz to 2.5MHz programmable range. Ensure the operating environment stays within the specified -40°C to +125°C temperature limits.
This part belongs to the MPQ4431 series of synchronous buck converters designed for automotive environments. It shares the same core topology and performance characteristics as other variants in the series, differing primarily in packaging or qualification grades. The series is engineered to meet the stringent reliability demands of automotive electronics while providing efficient power regulation.
MPQ4431GL-P is a non-automotive qualified variant with similar electrical specifications but lacks AEC-Q100 certification. MPQ4431GL-Z is another automotive-grade option within the same family. Verify pinout and thermal performance compatibility before substitution.
