PPS = Programmable Power Supply
With USB-PD 3.0, the previous power profiles with the fixed assignment of voltage and maximum current are replaced by flexible power rules. The higher the rated power, the more combinations are possible.
Programable Power Supply (PPS), allows USB power supplies not only to provide fixed steps above 5 volts, but also to dynamically run through wide voltage intervals. The power supply regulates the voltage in fine steps according to demand. The smartphone contains a regulator that transforms the voltage in a fixed ratio. Such regulators are inexpensive and also always work efficiently at the optimum operating point. The power supply constantly determines which voltage it should provide.
Without PPS, the smartphone must actively tell the power supply which combination of voltage and current is required.
