<p>A boost switching converter with multiple outputs includes an inductor is connected between an input supply (typically a battery) and a node Vx. A low-side switch connects the node Vx and ground. Two or more output stages are included. Each output stage includes a high-side switch and an output capacitor. Each output stage is connected to deliver electrical current to a respective load. A control circuit is connected to drive the low-side switch and high-side switches in a repeating sequence. The inductor is first charged and then discharged into each output stage. In effect, a series of different switching converters are provided, each with a different output voltage.</p> |
