Mobile devices are increasingly becoming power-hungry, and their power consumption values are significantly increasing. This gives rise to the need for fast charging. Every year devices like smartphones, tablets, etc., are getting more powerful.

Along with the processing speeds, the battery size is also increasing. Since heavy workload and day-to-day activities depend on these tools, the battery performance suffers greatly. So, efficient and safe fast charging is inevitable.

To meet this requirement, the Programmable Power Supply (PPS) was implemented to both the prevalent fast-charge standards, namely Quick Charge (QC) 4.0 and Power Delivery (PD) 3.0. In 2017, the USB-IF included PPS fast charging to USB PD 3.0 standard.

As a result, it created a combined solution for today’s fast-charging devices. In the same year, Qualcomm’s QC 4.0 was combined with the PPS standards, which resulted in a combined charging scheme.

Besides consumer products like laptops and mobile phones, PPS fast charging can also be used in power tools, servers, displays, and security POE power supplies.

Let’s get into in-depth details of PPS:

Programmable Power Supply (PPS):

PPS fast charging is regarded as the most innovative charging technology to charge USB-C devices. This technology adapts to the current and voltage in real-time, based on the charging status of an appliance. As a result, it feeds it with the maximum power.

PPS enables data transfer every 10 seconds. Therefore, it facilitates a dynamic fine-tuning of the output current and voltage depending on the conditions of the end device’s specifications.

In other words, it is a power supply that uses the USB PD protocol output to regular current and voltage. Moreover, this specification integrates the dominant two charging modes of low current and high voltage and high current and low voltage.

Furthermore, the PPS specification decreases the voltage amplitude modulation to 20mV (it is just one-tenth of QC3.0 standard; the voltage regulation is more accurate.)

To understand better, for example, while using a wall charger to charge your device’s battery, the voltage supply is transmitted to a battery charge control circuit.

Moreover, the corresponding system offers the appropriate current and voltage to charge the battery in your device. This works well when the system is standardized, but this is not the case every time.

After detecting the charging status of your device every few seconds, the PPS technology automatically adjusts to guarantee the most efficient power utilization. Also, it reduces the generated heat and maintains the lifespan of your device’s battery.

The primary benefit of using the PPS charging method is that it can continue fast charging without raising the expense of the cable. Once the battery gets charged, it generates enormous heat in your phone.

List of the devices that support PPS:

  • Samsung Galaxy 20
  • Samsung Galaxy Note 10
  • Samsung S20 Ultra
  • Samsung S21
  • Few laptop models support PPS

After understanding the overview and benefit of PPS, the question may arise, i.e., what changes it brings. Read the below section to know more:

What modifications did PPS bring?

PPS extends the USB interface’s output voltage range from 5V to 3.0V~21V.

The variable voltage range of PPS is 20mV. This range can obtain low-voltage and high-current direct charging.

PPS uses a pulsation system to guarantee the safety of the charging process. After the PPS operates in the high current mode, protection becomes so essential.

Hence, the PPS protocol specifies that for a minimum of every 10 seconds, there is a pulsating communication between the adapter and the load. This communication should be maintained to ensure the charging process stays in control.

Difference between PPS, PD, and QC:

PPS enables stepwise changes in voltage and current. It reduces the conversion loss during charging, ensuring the charge is more efficient.Power Delivery (PD) is a standard for handling higher power introduced by the USB Implementers Forum.Quick Charge (QC) is one of the most common fast-charging protocols on the market and is found in many popular smartphones.
Less heat is produced whenever the charge is efficient, which increases the battery’s lifespan.

When less heat is produced, a battery’s lifespan increases.

It allows devices to charge fast over a USB connectionQuick charge achieves fast charging by increasing the charging voltage, boosting the wattage in the process.
PPS fast charging is better for your device’s battery.This technology can deliver up to 100W power, which is more than sufficient for any smartphone.QC 3.0 is highly suitable for smartphones. Providing the exact voltage required lets you maximize your battery’s performance.

Let’s get more details about PD and QC charging standards:

PD Charging:

It can be used to charge laptops. For example, Apple’s latest MacBooks use it and can also be used when they are charging. It implies that you are receiving relatively better performance than you can anticipate from a standard USB cable.

Moreover, it delivers high-speed charging with adjustable voltage using intelligent device negotiation technology. This feature helps devices negotiate a power agreement to know how much power they can derive from a PD charger.

Apart from 100W power, PD Charging supports four other wattage levels. These levels are 7.5, 15, 27, and 45W. At every wattage level, there’s also support for various voltages.

PD is invented to let devices fast-charge on a USB connection. Its latest version, i.e., PD 3.0, is known as one of the most recognized fast charging protocols.

Note that PPS is the newest addition to the PD 3.0 standard. Also, PD and PPS protocols work flawlessly together in which PPS can renegotiate the non-standard voltages and currents between the charger and the device.

USB-C PD is the fast-charging technology supported by some Apple/iOS and Samsung/Android/Google devices, which deliver higher power levels than standard charging.

The maximum available power is 100W, so USB-C PD can charge huge devices like laptops and tablets. You require an appropriate wall charger and a USB-C cable—no need to use bulky laptop power cables.

PD charging is also perfect for laptops and other devices requiring higher wattages.

QC Charging:

Qualcomm Company which designs mobile CPUs invented QC Charging standard. This standard offers backward compatibility. This implies that a QC 3.0 device can be fast-charged with a QC 4+ charger.

Note that QC 5 is the newest standard available in the Quick Charge technology. It can recharge smartphones up to 50% capacity in five minutes.

The reason behind the wide popularity and high significance of the QC charging standard is that it needs a license. If a manufacturer doesn’t want to pay Qualcomm’s licensing fee, they can’t integrate QC 3.0 technology. Consequently, many devices that support PD charging can’t support QC charging.

QC charging technology can power your devices much faster than traditional charging, so you need to spend less time keeping outlets connected. One of the most extensively used fast charging technologies, the Quick Charge is already found in many of your favorite smartphones. For example, if your smartphone is QC 3.0-compatible, then it can charge up to 80% capacity in just 35 minutes.

QC 3.0 is identical to PD 3.0 because it provides enhanced charging performance to the standard USB. Like PD 3.0, the device and the charger should be compatible with QC 3.0 to let it work.

If your phone supports QC 3.0 technology but your charger doesn’t, you can’t attain any advantage. If you are charging an older phone via a QC 3.0 charger, you would only charge at standard USB rates.

The former versions, i.e., QC 1.0 and 2.0, were very efficient. However, QC 3.0 is 40% faster and only draws a little more power. It is implemented using Intelligent Negotiation for Optimum Voltage (INOV) technology.

It is expected that Quick Charge 4+ can work with USB PD. This enables Quick Charge accessories to fast charge a broad range of devices. Conversely, Quick Charge 5 is known to be the newest in QC standards, and it can recharge smartphones up to 50% capacity in only 5 minutes.

Most new Android phones support PD charging, and more than half of the Android phones (including the latest Samsung models) also support QC 3.0.
