Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments documentation. Confirm the WSON (NHN) package type matches your PCB footprint requirements. Ensure the adjustable output configuration aligns with your external resistor network design. Cross-reference the 16-pin pinout against your schematic to prevent installation errors during assembly.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an adjustable output voltage is required within the 8 V to 40 V input range. The 500 mA current capacity suits moderate load applications. Consider the WSON package for surface-mount designs where space is constrained. Verify that the 225 kHz to 275 kHz switching frequency meets your electromagnetic interference constraints and inductor selection criteria.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 series of SIMPLE SWITCHER® regulators. It shares the core buck architecture with fixed-output variants like the LM2674N-5.0/NOPB but offers adjustable output flexibility. The LD suffix denotes the WSON package variant, distinguishing it from through-hole or other surface-mount options within the same functional family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2674 series parts with compatible packages and electrical characteristics. Verify pin compatibility and thermal performance when replacing with adjacent package types. Ensure the replacement maintains the 500 mA output current rating and 40 V maximum input voltage specification.
