Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms RoHS compliance and absence of lead-based materials. Confirm the 'MX' designation indicates tape-and-reel packaging suitable for automated assembly. Ensure the part number matches the exact 12V fixed output variant rather than adjustable versions. Cross-reference the manufacturer date code to ensure availability aligns with production schedules.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from inputs between 6.5V and 40V. It is suitable for designs prioritizing simplicity due to low external component counts. Consider the 260kHz frequency for balancing size and efficiency. Verify that the 1A continuous current rating meets the load requirements without exceeding thermal limits in the SOIC-8 package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2672 SIMPLE SWITCHER family, which offers high-efficiency step-down regulation. It serves as a robust alternative to linear regulators by minimizing heat dissipation.
