Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes to confirm specific package variants and tape-and-reel quantities. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure design compatibility with automotive quality standards and check for any recent product change notices that may affect long-term availability or specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required for automotive loads up to 6 A. Consider the wide input voltage range for direct battery connection scenarios. Evaluate the switching frequency options against EMI constraints and inductor size limitations. Verify that the operating temperature range meets the specific environmental conditions of the target application zone.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM62460 family of automotive step-down converters. It shares core architecture with other variants in the series, differing primarily in output voltage configuration and packaging options. The Q1 suffix indicates automotive qualification, while the RPHR suffix specifies the 16-pin VQFN package and reel packaging type used for surface-mount assembly processes.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM62460QRPHRQ1 offers an adjustable output version within the same package and electrical envelope. LM62460Q5RPHRQ1 provides a fixed 5 V output alternative. These parts maintain pinout compatibility but require circuit redesign if the output voltage differs from 3.3 V.
