20120274295 | CURRENT MODE BUCK-BOOST CONVERTER - 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. | 11-01-2012 |
20130342183 | SWITCHING REGULATOR CONTROL CIRCUIT WITH MULTIPLE CLOCK FREQUENCY SETTING MODES - A control circuit of a switching regulator includes a control pin for coupling with an external resistor; a resistor detecting circuit for detecting a resistance of the external resistor; a current generating module for generating a corresponding control current according to a detection result of the resistor detecting circuit; an oscillating circuit for generating a clock signal; and a mode-switching circuit. When the mode-switching circuit configures the oscillating circuit to operate in a resistor-controlled mode, the oscillating circuit generates the clock signal according to the control current so that the clock signal has a frequency corresponding to the resistance of the external resistor. When the mode-switching circuit configures the oscillating circuit to operate in a signal-controlled mode, the oscillating circuit generates the clock signal according to an external synchronous signal coupled with the control pin so that the clock signal is synchronized with the external synchronous signal. | 12-26-2013 |
