Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes such as NOPB for lead-free compliance when ordering. Confirm that the SOIC-8 package variant matches your PCB footprint requirements. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check specific revision levels if strict compatibility with existing designs is required.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Choose this component for applications requiring a compact solution with minimal external parts. The fixed 260kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the input voltage never exceeds the 40V absolute maximum rating. Consider thermal performance under full load conditions given the 1A output capability.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2675 series of monolithic integrated DC-DC converters. The series includes fixed voltage options and other package variants like the through-hole LM2675N.
