Recently, the charging head network has obtained a Nubia Nubia white 20W dual port gallium nitride charger. Compared with dozens of 20W fast charging products previously disassembled, the biggest difference of this charger is the use of gallium nitride technology, which is indeed very rare in terms of this proportion.Charging head network learned that this charger adopts maorui core high-frequency QR power supply scheme, and the matched gallium nitride power chip is innoseco's second-generation new product inn650da04. Now let's disassemble this charger in detail to see how to design it.Previously, the charging head network has also disassembled Nubian white 65W double port gallium nitride fast charger, Nubian 30W gallium nitride fast charging, Nubian 120W 2c1a three port gallium nitride fast charging, Nubian 20W PD fast charging charger, Nubian 22.5w sugar fast charging charger and other products. Welcome to consult.Nubia's 20W charger adopts gallium nitride technology, which is quite rare in products of the same power level. The natural charger is positioned as a mini charger, and is equipped with 1a1c dual output interface, which is compatible with QC, AFC, FCP, SCP and PD3 0. PPS fast charging protocol meets the fast charging needs of mobile phones of apple, Samsung, Xiaomi and other brands.After disassembling the charging head network, it is found that the charger module adopts two small boards, adopts the maorui core mk2697a + mk91738 high-frequency QR switching power supply scheme, matches the innoseco inn650da04 gallium nitride power device, and the yingjixin ip2726 protocol chip controls the dual port output voltage. Zhongyuan and emerald capacitors conduct input and output filtering, and the overall material and workmanship are solid and reliable.
