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: Systems, methods, and circuitries are provided for generating an acceleration current in response to a threshold temperature being reached. In one example, temperature based acceleration current source circuitry includes a first temperature sensitive device, a second temperature sensitive device, differential trigger circuitry, and an acceleration current source. The first temperature sensitive device is configured to generate a first signal that varies responsive to temperature changes at a first rate. The second temperature sensitive device is configured to generate a second signal that varies responsive to temperature changes at a second rate. The differential trigger circuitry is configured to generate a trigger signal based on a difference between the first signal and the second signal. The acceleration current source circuitry is configured to output an acceleration current in response to the trigger signal.

Abstract: A timer for creating a stable on time. The timer may have a reference voltage source, and an input voltage source. The voltage sources providing voltage that can be applied to a various circuit components such as capacitors, inductors, resistors, diodes, transistors, or other components. The reference voltage source may also be modified by a set of transistors coupled as a diode before being seen by an input of a timer comparator. The reference and input voltage source signals, which may be modified by circuit components, are compared by the timer comparator and then output as a timer control signal. The timer control signal may control a voltage converter, or the switches of a voltage converter.

Abstract: Disclosed examples include inverting buck-boost DC-DC converter circuits with a switching circuit to alternate between first and second buck mode phases for buck operation in a first mode, including connecting an inductor and a capacitor in series between an input node and a reference node to charge the inductor and the capacitor in the first buck mode phase, and connecting the inductor and the capacitor in parallel between an output node and the reference node to discharge the inductor and the capacitor to the output node. For boost operation in a second mode, the switching circuit alternates between connecting the inductor and the capacitor in series between the input node and the reference node to discharge the inductor and charge the capacitor in a first boost mode phase, and connecting the inductor between the input node and the reference node to charge the inductor and connecting the capacitor between the first output node and the reference node to discharge the capacitor to deliver power to the output node in a second boost mode phase.
