USB Power Delivery PPS Adjusts Charging Voltage in Small Steps

USB-C describes a connector, but the connector alone does not determine charging speed. A phone, charger, and cable have to support a compatible power method before higher charging rates become available. USB Power Delivery, commonly shortened to USB PD, provides a negotiation system for this job. Programmable Power Supply, or PPS, adds a more flexible mode in which a compatible device can request power at adjustable voltage and current levels.
