Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LDX' against official Texas Instruments documentation to confirm it denotes the tape-and-reel packaging variant of the LM2675LD-ADJ/NOPB. Ensure the ordering part number matches the exact package type and reel quantity specified in the manufacturer's latest datasheet to avoid compatibility issues during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for 1A buck applications with inputs up to 40V. The WSON package offers a smaller footprint compared to SOIC or DIP variants. Consider the 260kHz frequency trade-off between component size and electromagnetic interference when designing the filter stage.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 series of SIMPLE SWITCHER regulators. It shares core electrical characteristics with other LM2675 variants but differs in package style. The LD suffix indicates the 16-WSON package, while the X suffix typically signifies reel packaging. It serves as a low-component-count alternative to linear regulators in medium-power applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2675LD-ADJ/NOPB is the direct equivalent without the reel suffix. LM2675M-ADJ/NOPB offers the same electrical performance in an SOIC-8 package. LM2675N-ADJ/NOPB provides through-hole mounting options. Verify pinout compatibility and thermal requirements when substituting.
