Mi 11 Pro/Ultra supports 67W wireless flash charging: as fast as wired charging https://www.duzline.com

On April 6, Xiaomi introduced in detail the 67W wireless charging supported by Mi 11 Pro and Ultra. It only takes 36 minutes to fully charge,

and the charging speed is zero time difference with 67W wired charging.

Officials pointed out that Xiaomi’s wireless fast charging architecture has gone through 4 generations of technology in 3 years,

from the Buck wireless charging architecture (charging power 5W-15W) starting from Xiaomi MIX 2S to the Buck + 2:1 charge pump wireless charging architecture (charging Power 20W),

and then to the 4:1 charge pump wireless charging architecture (charging power 30W-50W) adopted by Xiaomi 9 Pro, Xiaomi 10 and Xiaomi 11, our wireless charging technology has been leading the industry.

And Xiaomi 11 Pro and Ultra’s new self-developed 6:1 charge pump second charging architecture uses 6 times boost + low current to provide a unique and efficient way for high-power wireless charging.

New self-developed 6 times booster second charging architecture, how to achieve more efficient charging?

The official emphasized,

Although the principle is simple, it is very difficult to achieve a 6 times boost charging architecture. For this reason, we have customized two new chips.

Xiaomi breaks the limitation of traditional mobile phone charging chips working at 20V and customized the industry’s first 30V wireless charging chip.

This customized chip adopts advanced process, and design methods, to comprehensively, improve the switching characteristics, and conduction characteristics of the device,
