9.2 Typical Application
The TPS560430 only requires a few external components to convert from a wide voltage range supply to a fixed output voltage. Figure 18 shows a basic schematic.
Figure 18. Application Circuit The external components have to fulfill the needs of the application, but also the stability criteria of the device's control loop. Table 1 can be used to simplify the output filter component selection.
