8 Application and Implementation
Note
Information in the following applications sections is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI’s customers are responsible for
determining suitability of components for their purposes, as well as validating and testing their design
implementation to confirm system functionality.
8.1 Application Information
The LM5176 is a four-switch buck-boost controller. A quick-start tool on the LM5176 product webpage can
be used to design a buck-boost converter using the LM5176. Alternatively, Webench® software can create a
complete buck-boost design using the LM5176 and generate bill of materials, estimate efficiency, solution size,
and cost of the complete solution. Section 8.2 describes a detailed step-by-step design procedure for a typical
application circuit.
8.2 Typical Application
A typical application example is a buck-boost converter operating from a wide input voltage range of 6 V to 50 V
and providing a stable 12 V output voltage with current capability of 6 A.
