Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'QMR' against official datasheets to confirm package dimensions and thermal characteristics. Ensure the 'NOPB' designation aligns with RoHS compliance requirements for your manufacturing process. Confirm that the fixed 5.0V output matches the target load voltage precisely before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V rail is required from a higher bus voltage up to 42V. The 3A output capacity suits moderate load applications. Consider the 8-SO-PowerPAD package for thermal performance needs. Verify that the 500kHz frequency fits EMI constraints compared to lower-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22676 family of SIMPLE SWITCHER regulators. It shares core architecture with variants like LM22676MRE and LM22676TJ but differs in package type. The QMR suffix specifically denotes the 8-SO-PowerPAD form factor, distinguishing it from TO-263 or standard SOIC packages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22676QMRE-5.0/NOPB offers identical electrical specifications in the same package. LM22676MR-5.0/NOPB provides the same function without automotive qualification.
