Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and thermal characteristics. Ensure the supplier provides valid traceability documentation for automotive-grade components. Cross-reference the manufacturer part number with the latest revision history to avoid obsolete stock. Confirm RoHS compliance status through official certification records prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3 A buck converter is required within a 42 V input limit. The adjustable output allows flexibility for various load requirements. Consider the SO-PowerPAD package for its thermal performance in space-constrained designs. Verify that the 500 kHz frequency aligns with system EMI constraints or utilize the sync pin if necessary.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22670 family of SIMPLE SWITCHER regulators. It shares core architecture with variants like the LM22670QTJE but differs in packaging. The MR suffix indicates an 8-pin SO-PowerPAD format, distinct from the TO-263 packages used in other series members. This family emphasizes ease of design and high efficiency for general-purpose power conversion.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22670MR-5.0/NOPB offers a fixed 5.0 V output instead of adjustable. LM22670INVEVAL/NOPB is an evaluation board, not a direct replacement. LM22674MR-ADJ/NOPB provides only 500 mA output current. Verify pin compatibility and thermal dissipation requirements before substituting.
