Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix codes on the component marking against the official datasheet to confirm the fixed 3.3V output and AEC-Q100 qualification status. Ensure the QFN-16 package variant matches the intended PCB layout requirements. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, high-efficiency buck converter is required for automotive environments. It is suitable for applications needing stable 3.3V rails from higher bus voltages up to 36V. Consider its low IQ for battery-sensitive systems and the wettable flank feature for automated optical inspection needs in production lines.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MPQ9842 family of synchronous step-down converters designed for automotive applications. It shares architectural similarities with other MPS automotive regulators but is distinguished by its specific output voltage configuration and package type. The series emphasizes high-frequency operation to minimize external passive component size.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

MPQ9842GLE-33-AEC1-Z is a verified substitute offering identical electrical specifications and functionality. Both variants provide the same 3.3V output and 2A current capability within the automotive temperature range.
