Abstract: In accordance with an embodiment, a method includes receiving an indication of a changed load condition or voltage characteristic of a power supply providing power to a load via an output port of the power supply in a first mode, and switching regulation of the power supply from sourcing a current to the load in the first mode to sinking the current from the load in a second mode in response to receiving the indication of the changed load condition or voltage characteristic. Sinking the current from the load in the second mode includes controlling the power supply to transfer energy from the output port of the power supply to an input port of the power supply.

Abstract: In one example, a method includes determining, by a device of a system, a voltage feedback value that represents a voltage level of a power signal being provided to a plurality of load elements that are selectively active. In this example, the method also includes adjusting, by the device and based on a quantity of load elements of the plurality of load elements that are active, the voltage level of the power signal such that the voltage feedback value remains less than or equal to an overvoltage threshold.

Abstract: In one example, a system includes a load module, a power module, a series module, and a control module. The power module is configured to generate a supply power. The load module is configured to select a subset of light emitting diodes (LEDs) from a set of LEDs. The series module is configured to receive the supply power from the power module, dissipate a portion of the supply power, and output, to the subset of LEDs, a remaining portion of the supply power as a load power. The control module is configured to drive the series module to limit an amount of power at the subset of LEDs.

Abstract: Methods, devices, and integrated circuits are disclosed for applying an active output voltage discharge for a buck-boost converter. One example is directed to a method of operating a buck-boost converter that comprises an inductor, an output capacitor, and an output. The method includes receiving an indication of an altered output voltage requirement in the buck-boost converter. The method further includes deactivating a control loop in the buck-boost converter. The method further includes applying an active discharge of voltage from the output capacitor through the inductor to ground, thereby altering the voltage at the output of the buck-boost converter from a first output voltage to a second output voltage that corresponds to the altered output voltage requirement. The method further includes reactivating the control loop.

Abstract: A controller circuit for controlling a switching-mode power supply (SMPS) is configured to receive a load control signal indicating an on state when a load is to be coupled to the SMPS and an off state when the load is not to be coupled to the SMPS. In response to the load control signal transitioning from the on state to the off state, the controller circuit is configured to generate a first measured input voltage. In response to the load control signal transitioning from the off state to the on state, the controller circuit is configured to generate a second measured input voltage. The controller circuit is configured to drive a compensation voltage at a compensation element using the first measured input voltage and the second measured input voltage and selectively switch the SMPS using the compensation voltage after driving the compensation voltage.
