Overview
The LT8705AEFE#TRPBF is a high-performance synchronous buck-boost switching regulator controller manufactured by Analog Devices Inc. It operates with input voltages above, below, or equal to the output voltage, supporting a supply range of 2.8V to 80V and switching frequencies from 100kHz to 400kHz. The device features two outputs and two phases, utilizing a 38-TSSOP-EP package. It includes clock synchronization capabilities and control features such as enable, frequency control, and soft start, designed for robust DC/DC conversion in demanding environments.
Feature Summary
- Synchronous four-switch buck-boost topology for efficient power conversion across input/output voltage ranges
- Clock synchronization capability to reduce system noise and allow multi-phase operation
- Integrated control features including enable pin, frequency control, and soft start functionality
Applications
- Telecom voltage stabilizers
- Industrial distributed power systems
- Automotive electronics requiring wide input voltage ranges
Procurement Notes
Verify the specific suffix 'A' against the datasheet to confirm performance specifications differ from the standard LT8705EFE variant. Ensure the ordering code matches the required tape and reel packaging format. Confirm that the 38-TSSOP-EP package footprint aligns with the PCB design requirements before finalizing procurement orders.
Selection Notes
Select this component when an application requires a single controller to manage both step-down and step-up operations seamlessly. The choice is driven by the need for wide input voltage compatibility and the requirement for external MOSFET control rather than integrated switches. Consider the thermal performance of the exposed pad package for heat dissipation needs.
Part Context
This part belongs to the LT8705 family of buck-boost controllers from Analog Devices. It serves as a specialized solution for applications where input voltage fluctuates significantly around the output voltage level. The 'A' designation typically indicates a specific grade or revision within the product line, distinct from the standard EFE variant.
Replacement Considerations
LT8705EFE#TRPBF is a related model within the same family. Verify if the 'A' suffix denotes a specific electrical characteristic change or just a manufacturing lot variation before substituting.
