Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance per Texas Instruments specifications. Confirm the MX suffix corresponds to the SOIC-8 surface-mount package variant. Ensure the -12 designation matches the required 12V fixed output voltage. Cross-reference the manufacturer part number against official TI databases to validate authenticity and current production status before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input voltage ranging between 8V and 40V. The 1A output current capability suits moderate load applications. The 260kHz switching frequency allows for smaller passive components compared to lower-frequency regulators. Consider the SOIC-8 package for space-constrained surface-mount designs requiring through-hole compatibility alternatives like the N variant if necessary.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 series of SIMPLE SWITCHER converters, designed for high-efficiency step-down applications. It shares architectural similarities with the LM2674 and LM2676 but differs in output current ratings. The series emphasizes ease of use with minimal external components. The LM2675 specifically targets 1A loads, bridging the gap between lower-current and higher-current regulators in the portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2675M-12/NOPB: Identical function in SOIC-8 package. LM2675N-12/NOPB: Through-hole MDIP-8 alternative. LM2675LD-50/NOPB: WSON-16 package variant with different pinout; verify schematic compatibility.
