Disassembly report: chuangfuyuan Mini 33W 1a1c gallium nitride fast charging charger

2021-07-29

Chuangfuyuan Electronics Co., Ltd. is an OEM & ODM electronic design and manufacturer solution service provider with a full range of fast charging, applicable versions of global safety regulations, all-round power and a variety of innovative designs.

Recently, chuangfuyuan has launched a full range of PD fast charging products with power ranging from 20 to 120W, such as 20W Mini charging, 30W Mini multi port charging and 65W gallium nitride fast charging. The styles are rich and diverse to meet the purchase needs of customers. This charging head network will bring you the disassembly of chuangfuyuan Mini 33W gallium nitride fast charging. The product has fixed / folding pins and is equipped with 1a1c interface. Let's see how this charger is doing.

It is worth mentioning that, previously, the charging head network also disassembled the wealth creation source 65W 2c1a gallium nitride fast charging charger, which you can click the link to check.

When equipped with 1a1c interface, this mini 33W gallium nitride charger of chuangfuyuan has an overall size of only 31.5 * 32.5 * 34mm and a power density of 0.93w/cm ³， It is very compact to meet consumers' demand for 33W Mini charger.

The equipped 1a1c Wanjin oil interface can adapt to more equipment, support QC, AFC, FCP, PD and PPS fast charging protocols, have complete voltage gears of 5-20v, and two groups of PPS voltage gears of 3.3-11v3a and 3.3-16v2a, with good overall compatibility, and meet the fast charging needs of Android phones and tablets of major brands.

Through the disassembly of the charging head network, it is learned that the charger adopts the combination welding of two circuit boards, the L-shaped structure design, the capacitors, transformers and other devices are glued and reinforced, the capacitors are sleeved with insulating rubber sleeves, and the isolation plates are set between the primary stages.

The charger adopts Nanxin sc3021d master control, innoseco inn650da04 second-generation gallium nitride power device, and Shilan micro sd8525h synchronous rectifier chip to form a high-frequency QR switching power supply, and the cloud silicon semiconductor xpd738 protocol chip controls the dual port output voltage. Yongming small volume capacitor carries out high-voltage filtering, and the overall material is the mainstream.
