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. Customers should validate and test their design
implementation to confirm system functionality.
8.1 Application Information
The LM76005 is a step-down DC-DC converter. It is typically used to convert a higher DC voltage to a lower DC
voltage with a maximum output current of 5 A. The following design procedure can be used to select component
values for the LM76005. Alternately, the WEBENCH® software may be used to generate a complete design. The
WEBENCH software uses an iterative design procedure and accesses a comprehensive database of
components when generating a design.
8.2 Typical Applications
The LM76005 only requires a few external components to convert from a wide range of supply voltages to output
voltage, as shown in Figure 8-1 :

The LM76005 also integrates a full list of features to aid system design requirements, such as the following:
• VCC UVLO
• Programmable soft start
• Start-up tracking
• Programmable switching frequency
• Clock synchronization
• Power-good indication
Each system can select the features needed in a specific application. A comprehensive schematic with all
features utilized is shown in Figure 8-2 :
