Frequency Modulation Controller, Switch Mode Power Supply Including The Same, And Switching Operation Frequency Modulation Method
摘要：
The present invention relates to switching operation frequency modulation for reducing an output voltage ripple.The present invention uses a ripple of an input voltage so as to modulate a switching operation frequency of a switch mode power supply. A sensing voltage corresponding to the input voltage is received, a current ripple that is proportional to a difference between a peak value of the sensing voltage and the sensing voltage is generated, and a modulation control signal that is variable by the current ripple is generated. The present invention modulates a switching frequency by using an oscillator signal that is variable by the modulation control signal, and reduces the output voltage ripple.
摘要（中）：

本发明涉及用于降低输出电压纹波的开关操作频率调制。 本发明使用输入电压的纹波来调制开关模式电源的开关操作频率。 接收对应于输入电压的感测电压，产生与感测电压的峰值和感测电压之间的差成比例的电流纹波，并且产生由电流纹波变化的调制控制信号。 本发明通过使用由调制控制信号变化的振荡器信号来调制开关频率，并且降低输出电压纹波。
