A power conversion apparatus is provided. The power conversion apparatus of the invention includes a power conversion circuit and a control circuit. The power conversion circuit is configured to convert an input voltage to an output voltage. A detecting circuit detects a current flowing into a boot voltage input pin and converts the current into a corresponding detecting voltage. An adjusting signal generating circuit generates an adjusting signal according to the detecting voltage. A control circuit adjusts control parameters thereof according to the adjusting signal. The invention provides apower conversion apparatus which makes it possible to decrease the number of pins of a control circuit while maintaining normal operation of the power conversion apparatus. 本发明涉及种电源转换装置，其包括：电源转换电路、控制芯片、检测电路和调整信号产生电路，电源转换电路，以切换其自身的导通状态，而将所述输入电压转换为所述输出电压。检测电路检测流入靴带电压输入接脚的电流并将其转换为对应的检测电压。调整信号产生电路依据检测电压产生调整信号。控制芯片依据调整信号调整控制芯片的控制参数。本发明可在维持电源转换装置正常工作的情形下，减少控制芯片的接脚数目。
