December 27 news, Xiaomi will officially release the Xiaomi Mi 12 Pro tomorrow, this high-end flagship has a number of global debuts: the first second generation ltpo full screen, the first self-developed chip surging P1.
Among them, the surging P1 is a charging chip developed by Xiaomi, and Lei Jun, founder of Xiaomi and chairman and CEO of Xiaomi Group, said that "P1 fills the gap in the industry".
As the industry's first resonant charging chip, the Surging P1 has a 4:1 ultra-high efficiency architecture with adaptive switching frequency, with a resonant topology efficiency of up to 97.5%, a non-resonant topology efficiency of 96.8%, and a plummeting thermal loss of 30%.
At the same time, the surging P1 is also the 4:1 charging chip with the highest charging efficiency of Xiaomi, which can achieve ultra-high power density of 0.83W/mm, and LDMOS has also reached the industry-leading ultra-low 1.18mΩmm RSP.
The surging P1 chip needs to use three different withstand voltage FLY capacitors, each capacitor needs an independent open and short circuit protection circuit, and each operating mode needs to strictly control the precharge voltage, and the number of power tubes is nearly twice that of the traditional charge pump.
With the help of P1, Xiaomi Mi 12 Pro has achieved a single-cell 120W super second charge. Compared with the previous 120W fast charge on the Xiaomi Mi 10 Extreme Edition, the Xiaomi Mi 12 Pro's single-cell 120W second charge scheme is faster and saves more internal space.
In terms of specifications, Xiaomi Mi 12 Pro adopts a 2K OLED flexible screen, the first batch of Qualcomm Snapdragon 8 flagship processors, the rear main camera is 50 million pixels, and supports OIS optical image stabilization.
