Performance characteristics of QC3.0 charger


The first generation of the QC fast charging solution is called QC1.0, which increases the voltage and current to 5V2A. But as the screen becomes bigger and bigger, the body becomes thinner and thinner, and the battery life can't keep up. QC1.0 fast charging time is still long, and then QC2.0 and QC3.0 chargers have appeared one after another.

The current mainstream solution for fast charging is QC3.0 charger. The biggest feature of QC3.0 charger is that the voltage management mechanism is "INOV" (Intelligent Negotiation for Optimum Voltage), which allows the input voltage to start from 3.6V, with 0.2V (200mV) as the unit, combined with real-time The battery temperature, conversion efficiency, power and other factors are fine-tuned, and gradually increase or decrease within the allowable input voltage range (9V or 12V), unlike QC2.0, which can only be used in 5V/9V/12V. Two" violent choice.
The advantage of this is that the QC3.0 charger can greatly reduce the loss of the DC/DC conversion circuit, thereby effectively alleviating the heating problem during fast charging. According to Qualcomm, the QC3.0 charger can increase the efficiency by 38% compared to QC2.0, increase the charging speed by 27%, and reduce heat generation by 45%. A typical mobile phone can be charged from zero to 80% in about 35 minutes.
