Abstract: A conventional power supply device has a problem in miniaturization. A power supply device generates a prediction value of an error signal from first and second error signals, and controls an output voltage so that the prediction value lies between first and second threshold values. The first error signal is obtained by converting an error voltage based on the difference between the output voltage and a reference voltage at a first timing. The second error signal is obtained by converting an error voltage based on the difference between the output voltage and the reference voltage at a second timing.

Abstract translation: 传统的电源装置在小型化方面存在问题。 电源装置从第一和第二误差信号产生误差信号的预测值，并且控制输出电压，使得预测值位于第一和第二阈值之间。 第一误差信号是通过基于第一定时处的输出电压和参考电压之差的误差电压来获得的。 通过在第二定时将基于输出电压和参考电压之间的差的误差电压转换来获得第二误差信号。
