    Abstract: A dual-mode switching power control device includes an electric transformer, a PWM driving controller, a switching transistor, an isolation element, an output diode and an output capacitor. The PWM driving controller is connected to the switching transistor coupled to the electric transformer. The first side inductor of the electric transformer and the switching transistor are coupled to an input power, and the second side inductor of the electric transformer is coupled to the output diode. The output capacitor and a load are connected in series. The output power is converted into a feedback signal by the isolation element. The PWM driving controller determines to perform DCM or CCM based on the feedback signal to control the current flowing through the electric transformer, and the output power is generated. Therefore, the efficiency of power conversion is improved and is suitable for high power applications.

    Abstract: A synchronous rectifying buck-boost converter includes a controller, first and second transistors, an inductor and a capacitor. The controller is connected to the gates of the first and second transistors for controlling ON/OFF of the first and second transistors, and further controls the current of the inductor and charge/discharge of the capacitor. The first and second transistors connected in series are connected to the controller and the inductor. The inductor is connected to a first external power unit or a first external loading device. The drain of the first transistor is connected to a second external power unit or a second external loading device such that a low-voltage input power of the first external power unit is converted to a high-voltage output power or a high-voltage input power of the second external power unit is converted to a low-voltage output power.
