Disassembly report: Beisi 100W 2c2a gallium nitride second generation fast charging

2021-12-06

Baseus Beisi is a well-known consumer electronics brand in the industry. Many of its new products have become hot sellers once launched. Under the background of insufficient global production capacity, Beisi will choose to cooperate with multiple suppliers in order to continuously supply products to the market and meet consumer demand.

Recently, the charging head network has obtained a 100W 2c2a gallium nitride fast charge from Beisi, which is equipped with four 2a2c interfaces to support the maximum 100W fast charge. Charging head network has learned that this charger adopts LLC switching power supply architecture and LLC half bridge adopts super junction MOS products of Nanjing Huarui micro integrated circuit Co., Ltd. next, we will disassemble this product in detail to see the specific situation.

Previously, the charging head network has also disassembled Beisi 120W 2c1a gallium nitride fast charging charger, Beisi qc5 certified 100W gallium nitride fast charging, Beisi 30W super silicon charger, Beisi 20W super Si super silicon charger, Beisi 10000mah 1a1c two in one gallium nitride charger and other products. Welcome to consult.

Beisi's Pro version 100W gallium nitride charger has many highlights such as 100W high power, multi interface, blind plug, simultaneous fast charging of multiple devices, all mainstream fast charging protocols, portability and so on. It is a fast charging product with both performance and practicability. It is especially suitable for business travelers to meet the simultaneous charging needs of laptops, tablets, mobile phones and other devices.

Through the disassembly of the charging head network, it is found that the performance and internal structure materials of the product have basically not changed greatly. It is still the architecture design of PFC + LLC switching power supply and three-way DC-DC secondary step-down circuit. Only LLC half bridge adopts two Huarui micro hrm65r380g.

Huarui micro hrm65r380g is a multi-layer epitaxial process superjunction MOS transistor. It is packaged with dfn5x6, which can save space. It is mainly used in the field of PD fast charge and adapter in consumer electronics.

Huarui micro superjunction MOS has two processes: multi-layer epitaxy and deep trench. Medium and low voltage trench and Sgt MOS are widely used in consumer electronics (TV power supply / adapter / PD fast charging), LED lighting power supply, industrial power supply (PC power supply / server power supply / industrial equipment power supply / communication power supply, etc.), new energy vehicle charging pile, photovoltaic inverter (photovoltaic inverter grid connection system / small 5g base station, etc.) BLDC brushless DC motor drive, BMS lithium battery protection. Serve major customers in the above fields.
