While I waited for it to arrive, I tried to hunt down the technical details about how the QC3.0 protocol worked. Hugatry's blog was a great starting point for QC2.0, but I needed to learn how to set the other voltages as well. Given his success in mining the protocol info from datasheets, I went looking for the same. I found the datasheets for NCP4271-D and CHY103, which gave me the additional info that I needed. Snapdragon 8+ Gen 1 Mobile Platform | Latest premium-tier powerhouse | Qualcomm". www.qualcomm.com . Retrieved 2 June 2022. QC 3.0 can change exact voltage and can be anywhere between 3.7 and 20v, the charging is variable and this increases the overall efficiency of the charge. Iused 1kΩ and 4.7kΩ resistors to create voltage dividers that I could control with a microcontroller. With a voltage of 3.3V on top of the bridge, that would give me right around 0.6V in the middle. According to the data sheet I used, the signals levels we need are: 3.3V, 0.6V, 0V, or disconnected.
With these features, QC3.0 adapters offer a superior charging experience by providing faster speeds, wider compatibility, and enhanced safety. Whether you’re a busy professional, a frequent traveler, or simply someone who values convenience and efficiency, a QC3.0 adapter is an essential accessory to have for your compatible devices. Benefits of Using QC3.0 Adapter
What is Qualcomm Quick Charge?
Dynamic Voltage Adjustment: Once the voltage negotiation is complete, the QC3.0 adapter adjusts its output voltage to match the device’s requirements. QC3.0 supports multiple voltage levels, including 5V, 9V, and 12V, allowing for more efficient power delivery. This dynamic voltage adjustment ensures that the device receives the precise voltage it needs for optimal charging performance. Charging Speed: QC1.0 provided a charging speed that was up to 40% faster than conventional chargers. QC2.0 improved upon this, offering charging speeds that were up to 75% faster. However, QC3.0 raised the bar even further, allowing devices to charge up to four times faster than standard chargers and 38% faster than QC2.0. This significant improvement in charging speed makes QC3.0 the fastest charging technology among the three versions. On the other hand, Apple and Google Pixel phones are a bit different. Both of them use PD 3.0 only. As with Android devices, though, your performance will depend on your device. For example, older Apple devices like the iPhone 7 don’t support any kind of fast charging. But with the iPhone 8 and newer, you get full PD compatibility. Be aware that you won’t get any benefit whatsoever from a QC 3.0 charger. Apple phones simply aren’t compatible with the technology. So, which is faster, PD 3.0 or QC 3.0? In a nutshell, it depends on your device. To begin with, there’s a difference between Android and Apple products. With Android, you’re dealing with an open standard, so your mileage may vary. Most newer Android phones support PD charging, and more than half also support QC 3.0. This includes newer Samsung models. Keep in mind, though, that this will depend on your phone’s manufacturer. If you’re using a cheaper phone like an LG Stylo, you’re still limited to Micro USB charging. This won’t allow for either PD 3.0 or QC 3.0. To fully utilize the capabilities of a QC3.0 adapter, it’s important to use a USB cable that supports QC3.0. The cable plays a significant role in efficiently transferring power from the adapter to the device. A QC3.0-compatible cable should have a higher power carrying capacity to ensure optimal charging performance.
Safety and Protection: QC3.0 adapters incorporate advanced safety features to protect both the device and the adapter itself. The built-in safety mechanisms guard against overcharging, overheating, and power surges. This ensures the longevity of your device’s battery and prevents any potential damage or hazards during the charging process.Though USB power has gone from less than 1 amp of current (1 A) in its earliest incarnations to more than 2 A today, devices have maxed out the data and power capabilities of these connectors. using a larger transformer and thermal glue improve heat dissipation and keep components from vibrating.
Notebook บางรุ่นมีช่องชาร์จไฟบ้านเข้าแบบ USB-C แต่ก็ไม่รองรับเทคโนโลยี PD หรือ โดนล็อคไม่ให้สามารถชาร์จเข้าด้วย Charger อื่นได้) Avoid Extreme Temperatures: High temperatures can have a negative impact on the charging efficiency and overall performance of both the device and the adapter. Avoid exposing your device and QC3.0 adapter to extreme heat or cold, as it can affect the charging process and potentially cause damage to the components. Store and use the adapter and device in a cool and well-ventilated area.Efficient Power Transfer: QC3.0 adapters are designed to minimize power loss during the charging process. This results in more efficient power transfer from the adapter to the device, further enhancing the charging speeds and reducing wasted energy.
I am a layperson when it comes to QC 3.0 and USB-C information (I wrote this news post based on my research from what I considered reputable sources). You may be better served by asking your question to the experts, but I will do my best to answer your question as I understand it. Buy QC 3.0 accessories. The standard is pretty new, so you should get a good amount of use from them. INOV works by intelligently detecting the exact amount of voltage required by your device. This is a significant improvement from QC 2.0, which offered four different modes. By detecting the precise voltage your device needs, QC 3.0 provides two significant benefits. First off, it maximizes your charging performance. For instance, if your device requires an unusual voltage like 19 volts, the charger will deliver it. You won’t be left flat by a 12 or 18-volt charge. Secondly, the technology avoids any wastage. You won’t be feeding 20 volts of power to a 19-volt device. Not only does is avoiding waste good for the environment, it’s also good for your device. Excess energy is shed as heat, which can cause damage. By avoiding this, QC 3.0 prevents overheating. Which is Faster? It’s worth noting that while these devices can be charged using a QC3.0 adapter, the charging speed may vary depending on the device’s capabilities and requirements. It’s always recommended to refer to the device’s specifications or user manual to ensure compatibility with QC3.0 technology. Standard QC is 5V, QC2.0 Steps voltage at increments and QC3.0 has completely variable voltage across the range.PD 3.0 is a fast charging technology that was developed by the USB Implementers Forum. Because it’s an official part of USB technology, it can be supported by any manufacturer. No manufacturer has to pay extra licensing fees to incorporate PD 3.0 technology into their product. All they need to do is built the circuitry and the battery to the PD 3.0 specifications. This feature helps to reduce the amount of energy that’ll go to waste during charging. While charging your device, you might notice it heating up, this is the energy that goes to waste, and it can reduce your battery life span. The INOV feature ensures that lesser energy is lost, which means less heat. Fresco Logic to demonstrate the Industry's First USB-C PD3.0 Programmable Power Supply (PPS) Total Solution".
