Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix #06PBF against the manufacturer's latest documentation to confirm pinout compatibility and RoHS status. Ensure the TO-220-7 package variant matches your thermal management design. Cross-reference the part number with official Analog Devices distributors to avoid counterfeit components. Confirm that the 64V maximum input rating aligns with your system's transient voltage specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-voltage input range up to 64V is required alongside a robust 5.5A switch current capability. The integrated nature of the regulator reduces bill-of-materials complexity compared to discrete solutions. Consider the TO-220-7 package for through-hole mounting and adequate heat dissipation in industrial environments. Verify that the 100kHz switching frequency fits within your electromagnetic interference constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LT1074 family of switching regulators, which are designed for versatile DC-DC conversion tasks. The HV variant specifically extends the input voltage tolerance to accommodate higher source potentials. It serves as a direct replacement for older discrete switching regulator designs, offering improved efficiency and reduced board space through monolithic integration of critical control and power stages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LT1074HVIT#PBF is a documented substitute with identical electrical characteristics but may differ in packaging quantity or minor mechanical tolerances. Verify pin compatibility between the TO-220-5 and TO-220-7 variants if substituting across different package styles within the same family.
