Abstract: In one example, a circuit includes a voltage source, a pass module, a differential amplifier module, and a control module. The pass module is configured to electronically couple, using a channel having a resistance, the voltage source and a load and to modify the resistance of the channel based on a control signal. The differential amplifier module is configured to generate a differential signal based on a comparison of a voltage reference and a representation of a voltage at the load. The control signal is based on the differential signal. The control module is configured to generate the representation of the voltage at the load according to a transfer function. The transfer function includes a zero positioned substantially at a crossover frequency of the transfer function.

Abstract: A switching regulator with an output high threshold voltage setting and an output low threshold voltage setting that permits a plurality of different operating modes to be established. Combined with these two threshold voltages is the ability to adjust both threshold voltages over the full range of the regulator output voltage, which yields switching regulator modes of forced normal operation, automatic where the operating mode is dependent upon output current and forced sleep mode.

Abstract: A system and a method are disclosed for providing a dynamically configured low drop out regulator that has zero quiescent current and a fast transient response. A power supply control circuit is provided that comprises a switcher circuit and a low drop out regulator and a control signal circuit. When the output voltage of the low drop out regulator is in a steady state condition the control signal circuit generates control signals that turn off the operation of the low drop out regulator to provide zero quiescent current. When the output voltage is not in a steady state condition the control signal circuit generates control signals that turn on the operation of the low drop out regulator to provide a fast transient response.

In a state (1), a terminal Tx of a choke coil L1 is connected to an input terminal Tin, and a terminal Ty is connected to a reference potential. In a state (2), the terminal Tx is connected to the reference potential, and the terminal Ty is connected to an output terminal Tout. In the state (3), the terminal Tx is connected to the input terminal Tin, and the terminal Ty is connected to the output terminal Tout. A first period operation TO1 is constituted by the states (1) and (2), and a second period operation TO2 is constituted by the states (1) and (3). A second period T2, in which the second period operation TO2 is performed, is a value n times as long as a first period T1, in which the first period operation TO1 is performed. In the second period operation TO2, the state (1) is switched to the state (3) so that an increasing slope of an inductor current IL is reduced.

Abstract: A switching circuit operates with a first operating state and a second operating state. During the first operating state, the switching circuit allows a switching current to linearly increase. During the second operating state, the switching circuit allows the switching current to linearly decrease. A control circuit is coupled to the switching circuit for controlling the switching circuit to operate with the first operating state or the second operating state. A setting circuit generates a threshold signal for the control circuit to ensure that during the first operating state the switching current linearly increases to become higher than or equal to a current value set by the threshold signal. Thereby, the switching current is prevented from linearly decreasing to reverse polarity during the second operating state.
