Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix IT#PBF confirms the industrial temperature grade and lead-free tin-plated termination compliance. Confirm the TO-220-5 package style matches your thermal and mechanical design requirements. Ensure the 40kHz switching frequency aligns with your electromagnetic interference constraints. Validate that the 1.25A switch current meets your peak load demands without exceeding thermal limits.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring high input voltage tolerance up to 60V. It is suitable for applications needing flexible topology implementation such as isolated flyback or non-isolated buck designs. Consider the TO-220-5 package for through-hole mounting and adequate heat dissipation. Evaluate the 40kHz frequency against size constraints for external inductors and capacitors.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1072 family of high-efficiency switching regulators. It is distinct from lower voltage variants like the standard LT1072 due to its enhanced 75V switch rating. The HV designation indicates optimized performance for higher voltage industrial and commercial applications compared to general-purpose counterparts.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1072IN8#PBF offers similar electrical characteristics but uses a PDIP-8 package instead of TO-220-5. LT1072CS8 provides comparable functionality in an SOIC-8 surface-mount package. Verify pinout compatibility and thermal resistance differences when substituting these variants.
