Are you asking for compliance with a Samsung Note 10+? There's a heap of interest in 45W PPS compliant charger due to the 10 million units about to be in consumer hands. The issue to note is that there are 3 different PPS modes available under USB 3.0PD standards. The Note 10+ uses a 3.3-11V / 4.05A PPS mode. There are lower amperage PPS modes available (3.3-16V / 2.8A, and 3.3-21V / 2.1A) but with much higher voltages. The upside with the Samsung choice is that its low voltage is probably safer on electronics and easier to regulate in a 12V car charger... the downside is that you need a 5W "E-certified/Lightning 3" cable to make it work... and many chargers out there won't put out the 4-4,6 amps seen in Note 10+ charging. Most 45W USB-C PD3.0 chargers... EVEN WITH PPS... won't break 3 Amps. If they say "45W PPS charger" its likely at 2.8-3 Amps max.... and it'll max out at ~27W.
For reference, the USB-C PD3.0 modes are: PDO (Power Delivery Object) - this is the "normal" style. Most "high speed" charger will do 5V and 9V flavors: 5V / 3A 9V / 3A 15V / 3A 20V / 3A PPS (Programmable Power Supply) 3.3-11V / 4.05A - Note 10+ (aka Qualcomm Quick Charge 4+) 3.3-16V / 2.8A 3.3-21V / 2.1A
