摘要： A DCDC converter includes a controller, an up/down counter, a first power stage and a second power stage. The controller generates an up/down control signal. The up/down counter generates a first power stage control signal and a second power stage control signal based on the up/down control signal. The first power stage generates a first output current at a first phase and at a first voltage based on the first power stage control signal. The second power stage generates a second output current at a second phase based on the second power stage control signal. The up/down counter modifies the first power stage control signal to control the first power stage such that the first output current attenuates from a first power stage output to a secondary first power stage output. The controller can further output a control signal to modify the first voltage of the first power stage.

摘要： Described examples include DC to DC converters and systems with switching circuitry formed by four series-connected switches, inductors connected between the ends of the switching circuitry and corresponding output nodes, and with a flying capacitor coupled across interior switches of the switching circuitry and a second capacitor coupled across the ends of the switching circuitry. A control circuit operates the switching circuit to control a voltage signal across the output nodes using a first clock signal and a phase shifted second clock signal to reduce output ripple current and enhance converter efficiency using valley current control. The output inductors are wound on a common core in certain examples.

摘要： Disclosed examples include high-efficiency integrated circuits and inductive capacitive DC-DC converters with a first converter stage including first and second switches and an inductor, and a second converter stage including third and fourth switches and a flying capacitor. A dual mode control circuit regulates output voltage signal in a first mode when the output voltage signal is below a threshold by pulse width modulating the switches of the first converter stage. When the output voltage exceeds the threshold, the control circuit operates in a second mode with a first state to close the first and third switches, and a second state to close the fourth switch to connect the inductor in series with the flying capacitor. Dual mode operation of the first and second stages facilitates buck-boost operation with reduced inductor losses and converter switching losses, and the integrated circuit can be used in boost, buck or other configurations.

摘要： A controller for a DC-DC converter includes a state machine and a plurality of drivers for controlling switches in the DC-DC converter, where each state in the state machine determines a state of the drivers, and a plurality of timers, where each state in the state machine, other than a passive state, has an associated timer for the state of the drivers.

摘要： An inverting buck voltage converter constructed of a switched-mode hybrid topology, with a capacitive input stage and an inductive output stage. The input stage operates as a charge pump to charge a flying capacitor connected in series with an inductor in the output stage. Clock circuitry generates first and second non-overlapping clock phases. In the second clock phase, the flying capacitor is charged to the input voltage, with a flying node between the flying capacitor and the output inductor connected at ground through a rectifier, while in the first clock phase, the flying capacitor supports the inductor current. The arrangement of the flying capacitor and inductor is such that the voltage appearing at the output terminal is inverted from the input voltage. Continuous output current is provided. Current limiting techniques protect the flying capacitor from overcurrent conditions.
