摘要： A current mode buck-boost converter has an input terminal, an output terminal, and an output capacitor coupled to the output terminal. The input terminal is used to receive an input voltage, and the output terminal is for producing the output voltage. The current mode buck-boost converter comprises a voltage converter and a control circuit. The voltage converter comprises an inductor. The control circuit is for detecting the current passing through the inductor to determine the electric energy transmitted to the output terminal by the voltage converter. Accordingly, the current mode buck-boost converter has fast response, and the electrical energy can be recycled and stored to the voltage source when the current mode buck-boost converter operates in down-tracking process.

摘要： The present invention provides a voltage shifter circuit, in which a control circuit is used to control the pull-up circuit, so that the pull-up circuit is kept as off when the signal from the input signal source changes from a low voltage to a high voltage. Hence, the competition between the pull-up circuit and the pull-down circuit is avoided. The speed of the voltage shifter circuit is improved and the voltage shifter circuit can operate within a wider voltage range. The delay time of the pull-up circuit and the pull-down circuit is small and the duty cycle is small. In addition, since no direct current path is established, no current is wasted. Additionally, the voltage shifter circuit uses the second delayer to compensate the delay time between the pull-up circuit and the pull-down circuit and optimizes the duty cycle.
