Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB confirms RoHS compliance and absence of lead (Pb). Confirm the SD package designation matches the required VSON-14 footprint. Ensure the -3.3 variant corresponds to the specific 3.3 V fixed output requirement rather than adjustable or other voltage options.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V output is required from an 8 V to 40 V input source. The VSON-14 package suits space-constrained surface-mount designs. Consider the 260 kHz frequency for balancing component size and efficiency against noise requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2679 series of SIMPLE SWITCHER regulators, which are monolithic integrated circuits designed for high-efficiency buck conversion. The series includes various output voltage options and packages, such as TO-220 and D2PAK, but the SD variant specifically utilizes the compact VSON form factor.
