Abstract
In accordance with an embodiment, a method includes monitoring a first voltage across a buffer capacitor; activating a first current path between a power supply node and the buffer capacitor when the monitored first voltage is below a first threshold voltage, activating a second current path between the power supply node and the buffer capacitor when the monitored first voltage is below a second threshold voltage, and transferring power from the buffer capacitor to a driver circuit coupled across the buffer capacitor.
