Disassembly report: elambo 30W super Gan fast charging charger

2021-10-16

With the launch of iPhone 13 series mobile phones, charging head network also took the lead in conducting detailed charging evaluation. Test data show that the new model has made a significant breakthrough in charging power, especially the iPhone 13 Pro max, with a peak charging power of nearly 27W. In other words, the 20W PD fast charge recommended on Apple's official website can not fully meet the fast charge demand of the new iPhone, but also brings new opportunities for the development of the 30W PD fast charge market.

Elambo, a well-known power supply manufacturer in the industry, launched a 30W gallium nitride fast charging charger for iPhone 13 series fast charging. Thanks to the application of gallium nitride power chip, this charger realizes a mini body, the volume is equivalent to that of Apple's original 5W charger, and it is very convenient to carry. It is understood that this product has been shortlisted for the ces2022 product innovation award.

In terms of performance, in addition to the core USB PD fast charging protocol, this charger is also compatible with QC, AFC, FCP and other master fast charging protocols, and supports fast charging of mobile phones of multiple brands. At the same time, this product also adopts self-developed circuit, which has a strong price competitive advantage. Let's take a look at the internal materials of elambo 30W Mini gallium nitride fast charging charger.

Elambo 30W super Gan charger has a small shape, especially the American Standard pin and national standard pin versions. Compared with the traditional charger, its volume has obvious advantages; Single port output design is adopted, which can be compatible with a variety of mainstream fast charging protocols to meet the fast charging of mobile phones of apple, Huawei, Xiaomi, Samsung and other mainstream brands; At the same time, 30W power and up to 20V output can also be used for charging light and thin laptop, tablet computer, game console and other products. It is worth mentioning that the complete certification of the charger can accelerate the launch of brands and e-commerce customers and seize the first opportunity in the 30W PD fast charging market.

It is learned from the disassembly of the charging head network that the charger adopts a structure designed by the combination of three PCB boards. It is developed based on the second generation gallium nitride device of innoseco. At the same time, it also adopts Yongming small volume capacitor kcx series to achieve the maximum power output in a limited space. In terms of the protocol, the highly integrated chip xpd737 of cloud silicon semiconductor and built-in VBUS switch are selected to save the occupation of PCB board, Simplify peripheral circuit design.
