Disassembly report: Flash Retro 35W GaN charger

2024-09-27

Flash pays tribute to the legendary Macintosh of Apple, which launched a Retro 35W gallium nitride charger. This charger is designed according to the appearance of Macintosh. The shell is molded by high-precision injection molding, which has a delicate appearance. It restores the floppy drive, CRT screen and thermal slot of the Macintosh computer. The small and delicate appearance and the color matching with a sense of age make you feel as if you were back in 1984.

The charging head network has obtained the flash electrode 35W gallium nitride charger. Now we will disassemble it to show you the unique design of the charger and satisfy your curiosity.

In addition, the charging head network also disassembled the over flash 65W 1A1C gallium nitride charger, the flash 90W 2C1A gallium nitride fast charger, the flash 100W 3C1A gallium nitride fast charger, the flash 20W USB PD fast charger and other products. Welcome to consult.

The flash 35W GaN charger uses the classic Macintosh design to convey the charm of early technology products. The charger uses an analog computer display design to display the output state of the charger through different colors. The charger output supports 20V output, which is compatible with laptop charging. It also supports 33W PPS output, which is very compatible with Android and iPhone charging.

It is found from the disassembly of the charging head network that the flash electrode 35W GaN charger is composed of four PCBs by welding. The internal space is welded with high-voltage filter capacitors and transformers, and the PCB is hollowed out to output solid-state capacitors, making full use of space. The four PCBs are assembled and welded, and the structure is more reliable with the internal gluing. One PCB is welded with LED light equalizing plate for charging status display.

JW1515H+JW7726B GaN fast charging power supply scheme is used inside the charger, JW1515H supports direct drive enhanced GaN switch tube, and the peripheral circuit is simplified. The GaN switch tube is INN650DA04 from Innosaco, the synchronous rectifier tube is from China Resources Microelectronics, the protocol chip is Smart Rong SW2303, the VBUS switch is from Jiejie Microelectronics, the high-voltage filter capacitor is from Junkang, and the output solid state capacitor is from Bereker, all of which are well-known brands in the industry.
