Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer marking on the component body, as UMW may distribute TI-manufactured inventory or equivalent sourced parts. Confirm the suffix 'NOPB' indicates lead-free and RoHS compliance if required by your assembly specifications. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an 8V to 40V input source. It is suitable for designs needing 1A continuous current with moderate efficiency requirements. Consider thermal management solutions if operating near the upper limits of the input voltage or ambient temperature range within the SOIC-8 package constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 family of SIMPLE SWITCHER regulators, which are designed for high-efficiency buck conversion. The family includes variants with different fixed output voltages and adjustable versions. The LM2675 series is known for reducing external component count compared to traditional PWM controllers, offering a compact solution for general-purpose power management applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible replacements include other LM2675 variants with different output voltages (e.g., LM2675M-5.0) if the voltage requirement changes. For higher current needs, consider the LM2678 series. Verify that any substitute maintains the same SOIC-8 package and thermal characteristics.
