Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MX' indicates the SOIC-8 package variant when sourcing. Confirm RoHS compliance status as historical data may vary by production batch. Ensure the fixed 12V output matches design requirements, as adjustable versions exist within the same family. Cross-reference datasheet revisions for any pinout or electrical characteristic updates prior to final implementation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required without external feedback resistors. The 1A current rating suits moderate load applications. Consider the 275kHz switching frequency for EMI constraints. Compare against the adjustable LM2672MX-ADJ if variable output voltages are needed. Evaluate thermal performance in the SOIC-8 package for the specific PCB layout environment.
