Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as defined by the manufacturer. Confirm the package marking matches the 14-VSON specification. Ensure the ordering part number aligns with the required fixed 5.0 V output variant rather than adjustable or other voltage options within the LM2679 family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from an 8 V to 40 V input source. It is suitable for designs needing up to 5 A continuous current in a compact surface-mount footprint. Consider the 260 kHz switching frequency for balancing component size and efficiency requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2679 series of SIMPLE SWITCHER regulators, designed for straightforward DC-DC conversion applications. It represents the surface-mount VSON variant of the broader LM2679 family, which also includes through-hole packages like TO-220 and TO-263. The series is characterized by integrated power switches and minimal external component counts.
