11.2 Typical Application

The TPS2583x-Q1 only requires a few external components to convert from a wide voltage range supply to a 5-V output for powering USB devices. Figure 11-1 shows a basic schematic.

GUID-9A152B39-1166-4622-BB86-5AF83CD359AA-low.gifFigure 11-1 Application Circuit

The integrated buck regulator of TPS2583x-Q1 is internally compensated and optimized for a reasonable selection of external inductance and capacitance. The external components have to fulfill the needs of the application, but also the stability criteria of the device control loop. Table 11-2 can be used to simplify the output filter component selection.
