Disassembly report: Watson Mini 30W gallium nitride fast charging charger

2021-08-21

Facing the rapidly rising 30W Mini fast charging market, Shenzhen huakesheng Digital Technology Co., Ltd. has recently launched two products: Mini 33W fast charging and mini 30W gallium nitride fast charging. Although the former is a conventional CoolMOS scheme, huakesheng can still achieve 1.04w/cm of 33W charger ³， The company's R & D strength is quite strong.

The recently launched Mini 30W gallium nitride fast charge takes the power density one step closer to 1.12w/cm with the blessing of gallium nitride ³， The whole charger is quite small and at the front of the whole industry. In addition, the charger is compatible with fast charging protocols, has complete voltage gears, and is also quite practical. Next, the charging head network continues to disassemble this gallium nitride Mini charger to see how the materials are made.

It is worth mentioning that huakesheng also has mini 22.5w SCP fast charging charger, 65W 2c1a gallium nitride fast charging charger hpa-04n, huakesheng 65W 2c1a gallium nitride fast charging charger hpa-09n and other products for customers to choose from. The charging head network has also been disassembled in detail before.

Watson's Mini 30W gallium nitride fast charge has an overall size of only 34 * 27 * 27mm, which is very small. In addition, it is compatible with QC, AFC, FCP, pd3.0 and PPS fast charging protocols, with 5v3a, 9v3a, 12v2.5a, 15v2a, 20v1.5a, 3.3-11v3a and 3.3-16v2a voltage gears, super power density and strong performance to meet the fast charging needs of major brands of mobile phones, tablets and other devices.

It is learned from the disassembly of the charging head network that the charger PCBA module is composed of two small plates, and the components are glued for heat conduction and insulation. The charger adopts maorui core mk2697 master control, innoseco inn650da04 gallium nitride power chip and maorui core synchronous rectifier chip mk1718 switching power supply scheme. It adopts cloud silicon semiconductor xpd737 protocol chip and Yongming small volume capacitor filter. The overall material is good.

Up to now, huakesheng has 20W and 30W Mini chargers and 65W gallium nitride fast chargers in cylindrical and square shapes, which basically realize the full coverage of popular style chargers in the popular power section and fully meet the purchase needs of customers.
