Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the package type matches the 20-TSSOP-EP specification required for your PCB layout. Cross-reference the datasheet version to ensure compatibility with your design requirements.
Selection Notes
Select this component when a single IC must support multiple converter topologies such as SEPIC or ZETA. It is suitable for designs requiring input voltages up to 42 V. Consider the 20-TSSOP-EP package for thermal performance. Verify that the 10 A output current capability meets the load requirements of the target application.
Part Context
This part belongs to the LT8711 family of switching controllers. Related variants include LT8711EFE#PBF (lead-free, tube) and LT8711EFE. The series is characterized by micropower operation and multi-topology flexibility. It serves as a versatile solution for complex power management needs in automotive and industrial sectors.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Analog Devices resources for qualified alternatives.
