Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free status and RoHS compliance. Ensure the SOIC-8 package matches your PCB footprint requirements. Confirm that the 12 V fixed output aligns with system design needs, as other voltage options exist within the LM2597HV series. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from a wide input voltage range up to 60 V. It is suitable for applications prioritizing simplicity and efficiency over adjustable output flexibility. Consider the 500 mA current limit and 150 kHz switching frequency for thermal management and filter component sizing. Compare with adjustable variants if precise voltage tuning is necessary.
