电源单元的控制电路、电源单元及其控制方法
摘要：
本发明公开了一种电源单元的控制电路、电源单元及其控制方法。为了提供能够根据来自外部的指令灵活地设置和调节输出电压的电压值的电源单元的控制电路、电源单元及其控制方法，提供了用于将从外部输入的第一电压设置信息调节为实际电压信息的电压调节部分AD，并且基于从电压调节部分AD中输出的实际电压信息控制电源单元的输出电压的电压值。即使被设置为作为供电目的地的外部设备的输出电压的关于电压设置的信息不同于实际需要的电压值，通过灵活地调节实际电压信息，从外部输入的第一电压设置信息也使得所需要的输出电压能够被建立。
摘要（英）：

To provide a control circuit of power supply unit, power supply unit and control method thereof capable of setting and adjusting a voltage value of output voltage flexibly corresponding to an instruction from outside, a voltage adjusting portion AD for adjusting first voltage setting information inputted from outside to real voltage information is provided and the voltage value of the output voltage of the power supply unit is controlled based on real voltage information outputted from the voltage adjusting portion AD. The first voltage setting information inputted from outside enables a desired output voltage to be set up by adjusting the real voltage information flexibly even if information relating to the setting of voltage set as output voltage to an external device which is a supply destination is different from actually necessary voltage value.
