    摘要： The ON duration of an N channel MOS transistor is set based on a target voltage at a node between a resistor and a light receiving element of a photocoupler. A comparator compares the target voltage with a reference voltage at a node between a variable resistor and a resistor. A normal mode and a low frequency operation mode are switched from one to the other based on an output signal from the comparator. The resistance of the variable resistor becomes low when an input voltage from a power source is high. Even when the input voltage is high, therefore, the ON duration of the N channel MOS transistor at the transition between the normal mode and the low frequency operation mode becomes short. This reduces the switching energy in low frequency operation mode, thereby suppressing noise.

    摘要翻译： 基于光电耦合器的电阻器和光接收元件之间的节点处的目标电压来设定N沟道MOS晶体管的导通时间。 比较器将目标电压与可变电阻和电阻之间的节点处的参考电压进行比较。 基于来自比较器的输出信号，正常模式和低频操作模式从一个切换到另一个。 当电源的输入电压高时，可变电阻器的电阻变低。 因此即使在输入电压高的情况下，在正常模式与低频工作模式之间的转换时，N沟道MOS晶体管的导通时间变短。 这降低了低频操作模式中的开关能量，从而抑制噪声。

    摘要： A switching power source apparatus includes a switching element connected through a primary winding of a transformer to a DC power source, a start circuit for a control circuit, a rectify-smooth circuit of a voltage of a secondary winding of the transformer, and a rectify-smooth circuit to rectify and smooth a voltage of a tertiary winding of the transformer into a source voltage for the control circuit. The start circuit supplies a first starting current to start the apparatus and stops the first starting current once the apparatus has started. If the source voltage to the control circuit decreases to a turn-off voltage after the apparatus has started, the start circuit supplies a second starting current that is smaller than the first starting current. If the source voltage to the control circuit further decreases to a predetermined voltage that is lower than the turn-off voltage, the start circuit supplies the first starting current.
