Disassembly report: Aoji 65W 2c1a super silicon charger

2022-01-10

Recently, charging head network has obtained a 65W super silicon multi port charger from aukey Aoji. Although gallium nitride chip is not used, its power density has also reached 0.72w/cm ³ Mainstream standards. The charger is equipped with three interfaces of 2c1a, and the single port supports 65W, 20W and 18W fast charging respectively, which can meet the fast charging needs of two devices of laptop and mobile phone at the same time.

Charging head network learned that the built-in Biyi micro kp2202 + kp4060 power supply scheme of Aoji charger can be matched with the mainstream Gan power devices and CoolMOS devices in the market to develop gallium nitride fast charging products with high frequency, high efficiency and high power density. Next, the charging head network will disassemble this charger to see how its internal design and workmanship are.

Previously, the charging head network also disassembled Aoji 20W PD fast charging charger, Aoji 1a1c 32W fast charging charger, Aoji 63w gallium nitride fast charging, Aoji dual usb-c port 65W gallium nitride fast charging and other products. Welcome to check.

This 65W charger of Aoji has a high bright waist, rounded edges and corners, and good hand feel. In addition, it is easy to carry with foldable pins. It is equipped with 2c1a interface, compatible with QC, AFC, FCP, SCP, pd0 and PPS mainstream fast charging protocols, supports 45W + 20W / 18W dual port simultaneous fast charging strategy, meets the fast charging needs of apple, Xiaomi and other major brands of equipment, and is suitable for carrying out.

According to the disassembly of the charging head network, this charger adopts the Biyi micro kp2202 + kp4060 gallium nitride fast charging scheme, the maximum working frequency can reach 500KHz, and the built-in driver can drive the mainstream Gan switch tube, with strong and comprehensive functions. At present, Biyi micro has achieved mass production, which can help customers design gallium nitride fast charging products with strong performance and small volume to meet the needs of the market.

On this charger, Aoji is equipped with vian's super silicon MOSFET and synchronous rectifier. The output terminal uses two British Jixin ip2726 protocol chips to control the three port output of 2c1a. Nanxin sc8102 performs synchronous rectification and secondary voltage reduction for ports C2 and A. on the whole, the materials of this charger are also good.
