Abstract: A DC-DC converter circuit with selectable working modes is disclosed. Compared with the traditional chip that works in one mode, the DC-DC converter with selectable working modes adds only a mode selection circuit, so that the chip can work in voltage control mode or current control mode. On the one hand, the applications of the chip are more extensive, and on the other hand, when the applications are different, the cost of developing a DC-DC converter with selectable working mode is greatly reduced compared with the traditional DC-DC converter.
