Disassembly report: pengyuansheng 90W 1a1c gallium nitride fast charging charger

2021-12-30

Recently, pYS pengyuansheng High Tech Co., Ltd. launched a 90W gallium nitride fast charging charger for the high-power fast charging market, equipped with 1a1c wanjinyou interface, which supports 18W and 90W fast charging respectively, and also supports the 18W + 65W dual port simultaneous fast charging strategy. Double port fast charging, high power, small and portable, pin replaceable and other advantages of the product, fully meet various needs of consumers. Below, the charging head network will disassemble this fast charging in detail to see how the materials and workmanship are.

It is worth mentioning that the charging head network has removed several products such as pengyuansheng 30W PD fast charging charger, pengyuansheng 20W PD fast charging charger, pengyuansheng folding pin 20W PD fast charging charger, pengyuansheng 65W PD gallium nitride fast charging, pengyuansheng 65W 1a1c gallium nitride fast charging charger, etc. welcome to consult.

Pengyuansheng 90W gallium nitride fast charging adopts PC flame retardant material shell, supports 110-240V wide range voltage input, and the compact body and other specification pins other than American regulations can be assembled, which makes this charger very suitable for business people. Equipped with 1a1c dual output port, compatible with QC, AFC, FCP, SCP and Pe2 0、PD3. 0. PPS is a mainstream fast charging protocol with good compatibility, which can be adapted to most brands of laptop, tablet and mobile devices on the market.

Through the disassembly of the charging head network, it is found that in order to deal with the heating problem caused by high-power fast charging, sufficient heat dissipation measures have been taken inside the charger. The module is glued and pasted with heat conduction pad, and then wrapped with heat dissipation copper foil to ensure that the charger can rise and charge quickly at high power and low temperature.

The charger is designed with PFC + QR switching power supply architecture. The PFC boost circuit is composed of ansenmey ncp1622 and innoseco gallium nitride device inn650d150a. Tyco Tianrun g3s06503c silicon carbide diode rectifier is also used.

The switching power supply adopts ansenmey ncp1343 + MPs mp6908a high frequency QR switching power supply scheme, and the primary switch tube also adopts innoseco inn650d150a. The output end adopts yingjixin ip6525s and ip2723t to control the output of port a and port C respectively. The overall workmanship and materials of the charger are solid and reliable.
