Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'P' indicates the reel packaging configuration as documented by the manufacturer. Confirm that the component meets the required AEC-Q100 grade specifications for your target automotive application. Ensure compatibility with the QFN-12 footprint during PCB layout. Cross-reference the datasheet revision date to ensure all electrical characteristics align with your design requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60 V is required in a small form factor. The 2.2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. The extended junction temperature rating of 150°C provides robustness in high-thermal environments typical of automotive under-hood or chassis-mounted locations.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MP4573 series of synchronous step-down converters designed for demanding power management applications. It shares architectural similarities with other MPS automotive-grade regulators but is distinguished by its specific 60 V input capability and 2.5 A current rating. The series is engineered to meet stringent automotive quality and reliability standards.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include MP4573GQBE-Z and MPQ4573GQBE-P, which share identical electrical specifications and pinouts. Verify that any replacement maintains the same AEC-Q100 qualification status and thermal performance characteristics.
