PPS Is The Hottest USB-C Feature You Didn’t Know About
1 min read
Summary
Programmable Power Supply (PPS) allows USB-C devices to request variable voltage and current delivery from its charger.
This means it is not limited to the 5V, 9V, 15V or 20V voltages offered by standard USB chargers, and can demand the exact amount it needs.
This is especially useful for fast-charging smartphones, and allowing them to charge at the optimum voltage.
However, there is not much compatibility with PPS, with few breakout boards or accessories supporting the standard, unlike standard USB Power Delivery (PD).
Chargers with Added Voltage Stabilisation (AVS) offer even more voltage, but are rare and theExact increments are less precise.
