3.4 Adjusting the Cable Compensation Value

The TPS25859-Q1 must short the VSET pin to ground to enable the cable compensation. With that setting, the buck regulator increases its output voltage linearly as the load current increases, and the voltage compensation at currents of the USB ports greater than 2.4 A is 90 mV.
