TPS63020的输出电压可以超到8V?

标称的最大输出电压是5.5V..可是DATASHEET上有这样一句话
When the adjustable output voltage version TPS63020 is used, the output voltage is set by the external resistor
divider. The resistor divider must be connected between VOUT, FB and GND. When the output voltage is
regulated properly, the typical value of the voltage at the FB pin is 500mV. The maximum recommended value
for the output voltage is 8V.
那么可以超到8V??
如果调到6V的话会对电源造成什么样的影响呢??主要考虑纹波和电流的影响
