    • According to an aspect of the present invention, a converter converts an input signal to a square wave signal using at least one switch and generates an output voltage using the square wave signal. The converter includes: a switch control unit which generates the output voltage by converting the square wave signal by the switching operation of the switch and to which controls the switching operation of the switch. According to the output voltage, the switch control unit generates a first signal (VCT) having a first period variable; controls the switching operation of the switch using the first signal; detects an output current, a first current (Ids2) flowing on the switch, and the level of the first signal; and controls a bust mode according to the result of the detection.
    • 根据本发明的一个方面,转换器使用至少一个开关将输入信号转换成方波信号,并使用方波信号产生输出电压。 该转换器包括:开关控制单元,其通过由开关的开关操作转换方波信号并且控制开关的开关操作来产生输出电压。 根据输出电压,开关控制单元产生具有第一周期变量的第一信号(VCT); 使用第一信号控制开关的开关操作; 检测输出电流,在开关上流动的第一电流(Ids2)和第一信号的电平; 并根据检测结果控制胸围模式。
