RoadTest: InnoSwitch 3-Pro GaN Controllable USB Power Supply
Evaluation Type: Power Supplies
Did you receive all parts the manufacturer stated would be included in the package?: True
What other parts do you consider comparable to this product?: Reference Design Kit, INN3377C-H301/PIC16F18325, Programmable Industrial Power Supply
What were the biggest problems encountered?: I believe that this module should be accompanied by a protective case, so that we do not risk touching the circuits when we use it, there is a danger of high voltage.
The technology used to charge phones has evolved a lot in recent years, the capacity of the phone's battery has increased due to the needs of users who spend more and more time on the phone, and to the same extent, manufacturers have had to come up with a solution to charge more. quick.
Fast charging protocols such as USB PD (USB Power Delivery) are among the newest technologies on the market, they significantly reduce the battery charging time for a mobile phone, from overnight charging that we all use to less than 30 minutes. This makes charging faster and more convenient for the user, who accesses the phone daily for a long time.
USB PD is set to become the new standard for charging mobile devices. USB PD chargers have a power of up to 100 W, which makes it possible to use a single charger in the near future, both for mobile phone and tablet and laptop.
I am very excited to be able to use a device from Power Integrations, a very good electronics company, which brings to market various high quality and high performance power supplies for both mobile phones, laptops and home appliances. Following the participation in this Road Test supported by the Element14 Community, I have the opportunity to experiment with a 60W USB PD 3.0 power supply, capable of supplying several DC output voltages: 5V 9V 15V and 20V all at a constant current of 3A, which it is very useful. The input voltage is alternative, 85-265 VAC, wide coverage. The power supply automatically selects the output voltage, depending on the load need. Also, I'm not afraid to use it, because this device has overvoltage and overcurrent protection, in addition to thermal protection. The main use of this power supply is for mobile phones, but as I said above in this presentation, this device can be used successfully as a power source for many electronics and home appliances.
I will start by expressing my first impression when I opened the package; I quickly open the package, I find a power supply kit, I notice plugs for all possible sockets, type A, C, G, H, a cable, and a box, in this box is the main part, namely 60W USB PD 3.0 power supply. The manual with instructions for use and other information is digital, ie, on the box where the module is located we find a QR code that if we scan it, it will send us to a web page with the catalog data of the product, plus many other information. Power plugs are detachable, C7 Female To C8 Male 2-pin power cord, that's why we have detachable heads, I'm from Europe, so I use type C. It's a cable labeled Special Use, and it's 2 meters long, enough long. Returning to the 60W USB PD 3.0 power supply electronic module, I notice a rather compact, well-knit module, the C8 male connector is well glued, solid, as well as the USB Type-C connector. On top we have a transformer, a large capacitor and a few other THD components, and on the bottom we have most of the components that are obviously SMD. Do not notice wiring holes in the wiring, it would have been necessary; maybe power LED indicator; I have to mount the module in a case, it's not safe to use it for too long without protecting it, but for now I can handle it. This module weighs approximately 68 grams; the length and width of the plate respect what I read in the catalog data, the height as well. The manufacturer recommends that if we use a housing, we must install a thermal pad, "U" shaped radiator and be sure to provide the module with the appropriate materials. We find all these instructions in the catalog, even with suggestive images.
In terms of technology and components used to make the InnoSwitch3-Pro INN3379C-H302 IC circuit, it also provides protection features, in case of AC input undervoltage or overvoltage. Weltrend WT6635P is USB PD controller; WT6635P communicates with InnoSwitch3-Pro IC through the I2 C interface using the SCL and SDA lines in which it sets the CV, CC, Vkp, OVA and UVA parameters. These parameters correspond to the output voltage, constant output current, constant output power voltage threshold, output overvoltage threshold, and output undervoltage threshold registers of the InnoSwitch3-Pro IC, respectively.
In use, I did not notice overheating and the circuit, well, I used to charge my mobile phone that has USB Type-C input.
At the moment I don't have another USB Type-C powered device, but that's not a problem, I'm sure I'll find something.
It is a good product manufactured by Power Integrations, very useful, which can be used as a power supply for a wide range of electronics and appliances, phones, tablets, laptops and more, even if the main use room is the charger for the mobile phone.
I am satisfied with this Road Test. Good luck. Element14 Community does a good job.
