Audio giants enter the gallium nitride market, Harman Caton infinitylab 65W Gan fast charge disassembly

2021-12-06

Harman / Kardon is a department of Harman international industry, specializing in the production of household and vehicle audio. It was founded in 1953 and headquartered in Woodbury, New York, United States. At the same time, JBL, AKG and infinity are also brands under Harman group. Infinity lab is a brand of Harman Caton, focusing on power related accessories.

Recently, the charging head network has obtained an infinitylab 65W gallium nitride fast charge. This charger has a built-in gallium nitride switch of Gan systems, which is very compact as a whole. Moreover, equipped with 1a1c dual output, it can meet the simultaneous charging of two equipment, improve charging efficiency and save time.

Gan systems was founded in Ottawa, Canada in 2008. Its products have maintained a good reputation among customers in different industries. The apple 140W gallium nitride charger disassembled by the charging head network recently has built-in two enhanced gallium nitride switches of Gan systems, which can enter the apple fast charging supply chain, which shows that the chip of Gan systems is quite excellent in both performance and quality.

The infinitylab 65W gallium nitride charger, supported by Gan systems gs-065-011-1-l gallium nitride power tube, is very compact as a whole, and the three-dimensional is only 56 * 56 * 29mm. In addition, another feature of the charger is that the pins can be removed and replaced. This makes the product not only compact and portable, but also has three specifications in the United States / Britain / Europe, and the pins can be replaced at will. It is very suitable for business people who often travel. It can be charged from laptop to headset, with good practicability.

Through disassembly of the charging head network, it is found that the charger adopts ansenmey ncp1342 + MPs mp6908 power scheme, with Gan systems gs-065-011-1-l gallium nitride power tube and hengtaike synchronous rectifier, Weiquan wt6636f protocol chip controls the output voltage of port C, and the usb-a port uses eup3271 secondary voltage reduction to output at 5V constant voltage. Aihua and wanjingyuan brand capacitors are used for input and output filtering, and the overall material of the charger is very good.

Thanks to the use of Gan systems gs-065-011-1-l gallium nitride power tube, the charger is not only compact, but also performs well in efficiency and temperature rise. There is no need to use heat conduction pad and heat sink to help heat dissipation.
