Preset two voltages, the default output is 5.2V (can compensate for the line loss when charging electronic products such as mobile phones to achieve a larger charging current), and the output voltage can be adjusted to 3.3V by using the soldering iron to disconnect the pad. The EN control pin is pulled out, the default high level has output, and there is no output when low level. The FB pin is pulled out and the output voltage can be changed by changing the voltage dividing resistor of FB. The voltage is calculated as follows:
