Procurement Notes
Verify the specific suffix #06 against official Analog Devices documentation to confirm pinout or marking variations. Ensure compatibility with TO-220-5 mounting requirements. Cross-reference thermal dissipation needs given the 5.5A switch current capability. Confirm RoHS compliance status via the manufacturer's latest material declaration before integration into regulated assemblies.
Selection Notes
Choose this component when high input voltages up to 64V are required alongside substantial output current capabilities. The integrated nature reduces external component count compared to discrete solutions. Consider the TO-220-5 package for adequate heat dissipation in through-hole layouts. Evaluate thermal management strategies due to the high power handling characteristics inherent in the design.
Part Context
This part belongs to the LT1074 series of switching regulators, which are designed for robust performance in industrial environments. The HV variant indicates extended voltage tolerance suitable for higher input rails. It serves as a core power management IC for systems requiring flexible topology implementation without complex external control loops.
Replacement Considerations
LT1074HVIT#PBF is listed as a parameter equivalent alternative. Verify functional equivalence regarding pin configuration and electrical specifications before substitution.
