| abstract | A power supply circuit that can obtain a constant output voltage even when a supply voltage fluctuates in a wide range and can be downsized is provided. A power supply circuit according to the present invention includes a charge pump circuit 1a, a comparison operation circuit 2, and a switch control circuit 3a. The charge pump circuit 1a includes a boost capacitor C1 and a boost capacitor C2. The comparison operation circuit 2 and the switch control circuit 3a control charging voltages (voltage V1 and voltage V2) of the boost capacitor C1 and the boost capacitor C2. The power supply circuit outputs a constant output voltage Vout1 based on the voltage V1 and the voltage V2. [Selection] Figure 1 |
