Procurement Notes
Verify the specific ordering suffix to ensure the correct packaging format. The #PBF suffix indicates lead-free RoHS compliance and halogen-free construction. Confirm that the TSSOP-16 package matches the target PCB footprint requirements. Ensure the supplier provides valid traceability documentation for component authenticity.
Selection Notes
Select this controller when a wide input voltage range and high output capability are required. It is suitable for designs needing flexibility between step-up and step-down operations without changing the core control IC. Consider the current-mode architecture for robust transient response. Verify that the external MOSFET selection aligns with the drive capabilities and voltage ratings specified in the datasheet.
Part Context
This component belongs to the Linear Technology (now Analog Devices) family of high-voltage DC/DC controllers. It is part of a series designed to reduce part count and cost while maintaining high efficiency. The device integrates essential control functions to simplify the design of complex power conversion stages.
Replacement Considerations
Check for direct pin-compatible alternatives within the Analog Devices portfolio. Verify that any substitute maintains the same input voltage range and topology support. Ensure thermal performance and package dimensions remain compatible with the existing design constraints.
