8.2 Typical Application
The LMR54410 only requires a few external components to convert from a wide voltage range supply to a fixed output voltage. Figure 8-1 shows a basic schematic.
Figure 8-1 Application CircuitThe external components have to fulfill the needs of the application and the stability criteria of the control loop of the device. Table 8-1 can be used to simplify the output filter component selection.
