    Abstract: A multi-phase buck-boost converter includes a first half-bridge circuit, a second half-bridge circuit, a third half-bridge circuit, and a control circuit. The first half-bridge circuit is coupled to a first inductor terminal. The second half-bridge circuit is coupled to a second inductor terminal. The third half-bridge circuit is coupled to a third inductor terminal, a system voltage terminal, and a battery terminal. The control circuit is coupled to the first half-bridge circuit, the second half-bridge circuit, and the third half-bridge circuit. The control circuit is configured to transition the first half-bridge circuit, the second half-bridge circuit, and the third half-bridge circuit from operation in a buck mode to operation in a buck-boost mode based on an off-time of the first half-bridge being less than a particular time.

    Abstract: A voltage regulator control circuit includes a transistor input controller. The transistor input controller forces a slew control signal on its slew control output to a state responsive to a change in a load condition and forces an ON signal to a state on its first transistor control output. A first transistor has a first control input and first and second current terminals. A second transistor couples to the first transistor. A driver has a slew control input, a driver input, and a driver output. The driver input couples to the first transistor control output. The driver output couples to the first control input. Responsive to a first logic state of the slew control signal and a first state of the ON signal, the driver provides a higher current to the first control input, and responsive to a second state of the slew control signal and a first state of the ON signal, the driver provides a lower current to the first control input.

    Abstract: A voltage regulator module may comprise a control signal generation module, a power stage, and a routing network. The control signal generation module may be configured to, in a first mode of operation, generate an internal control signal for controlling the power stage. The routing network may be configured to, in the first mode of operation, apply the internal control signal to a control node of the power stage. The routing network may be configured to, in a second mode of operation, electrically connect said control node to an input pin of the voltage regulator module such that the power stage is controllable by an external control signal applied to said input pin. Thus, in the second mode of operation, it becomes possible to control the power stage directly via the external control signal and use this power stage e.g. as a single phase of a multi-phase power converter.
