Quick Charge 3.0 Charger Lower Calorific Value Is More Efficient

Estar Industrial Group Co.,Ltd | Updated: Sep 25, 2017

QC3.0 is simply an optimized version of QC2.0, is a lower calorie, more efficient QC2.0. The original QC2.0 is the output voltage: 5V, directly rose to 9V or 12V, 20V. Very direct effect. Due to the relationship between the pressure, the efficiency will be reduced, increased heat, charging time increases. So have the QC2.0 version of the optimization: QC3.0.

The following is the use of QC3.0 fast charge identification IC (FP6601Q) + AC-DC power IC (PL6650) together with the power. FP6601Q can also be used in car charger, mobile power, charger, wall mount, etc. USB port applications.

1.QC3.0 fast charge the characteristics of the agreement:

QC3.0 compared to QC2.0 is more subtle point, the output voltage between 3.6V to 20V. Output voltage change is ladder type: 0.2V a section up or down, while compatible with QC2.0 directly rose 9V, 12V, 20V character. Or because of the relationship between the pressure, QC3.0 than QC2.0 efficiency will increase, reduce the heat, charging time is reduced. (According to Qualcomm, QC3.0 can increase the efficiency of QC2.0 by 38%, increase the charging speed by 27%, reduce the heat by 45%, and get a typical mobile phone from zero charge to 80% in about 35 minutes.

2.FP6601Q is QC3.0, QC2.0 and Huawei Haisi fast charge (FCP) identification chip, the most complete function. In itself to support QC3.0, QC2.0 and Huawei Haisi fast charge (FCP) in the case. Also added USB auto-recognition function: APPLE, Samsung, BC1.2 protocol. If the phone supports fast charging protocol, the charger will charge in fast mode; if the phone does not support the fast charging protocol, FP6601Q can automatically identify the inserted phone, automatically adjust the D +, D-voltage, enable the phone itself to allow the maximum charge current, Charge the phone (a simple understanding is: is equivalent to the original charger to the phone charge.
