PRODUCTION DATA
The TPS2585x-Q1 only requires a few external components to convert from a wide voltage range supply to a 5-V output to power USB devices. Figure 11-1 shows the TPS25850-Q1 typical application schematic for Dual Type-C charging ports.
As a quick start guide, Table 11-1 provides typical component values for some of the most common configurations. The values given in Table 11-1 are typical. Other values can be used to enhance certain performance criterion as required by the application. The integrated buck regulator of TPS2585x-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 control loop of the device.
