    Abstract: An example of a power supply system includes a switching voltage regulator comprising at least one switch configured to conduct an input current to generate an output voltage responsive to a switching signal and based on an input voltage. The system also includes a current regulator configured to generate a current sample voltage based on an amplitude of the input current relative to a reference current defining a maximum average amplitude setpoint of the input current to set a switching time defining a switching period of the at least one switch. The system also includes a switch controller configured to provide the switching signal to control the at least one switch based on an amplitude of the output voltage relative to a reference voltage and based on the switching time.

    Abstract: In a circuit for DC-DC voltage converters, an amplifier has first and second inputs coupled to a reference voltage terminal and an output voltage terminal, respectively. A comparator has first and second inputs coupled to an amplifier output and a switching terminal, respectively. A logic circuit has inputs coupled to the comparator output and a clock terminal. A driver circuit has first and second inputs coupled to first and second logic outputs, respectively. A first transistor having a first control terminal coupled to the first driver output is coupled between a supply voltage terminal and the switching terminal. A second transistor is coupled between the switching terminal and a ground terminal, and has a second control terminal coupled to the second driver output. A threshold detection circuit is configured to provide a threshold signal responsive to a current through the second transistor crossing a current threshold.
