Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB confirms lead-free and RoHS compliance. Confirm the -3.3 variant provides the specific fixed output voltage required. Ensure the SOIC-8 package matches the PCB footprint. Check for active status as some variants may be discontinued.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 3.3V output is needed with up to 1A capacity. It suits designs prioritizing low component count over adjustable flexibility. Consider the 260kHz frequency for balancing size and efficiency. Verify input voltage stays within the 8V to 40V operational window.

Voltage Regulators - DC DC Switching Regulators Part Context

Part of the LM2672 SIMPLE SWITCHER family, designed for high-efficiency buck conversion. It integrates a 1A switch and controls into a single IC. The series targets applications requiring robust performance in compact spaces with minimal external passive components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2672M-3.3/NOPB is the direct equivalent. LM2672M-ADJ/NOPB offers adjustable output instead of fixed 3.3V. LM2672MX-3.3/NOPB uses a smaller MSOP-8 package. Cross-reference pinouts and thermal characteristics before substitution.
