Abstract
An apparatus for power supply mode switching includes a first voltage regulator to output a first voltage, a second voltage regulator to output a second voltage, a third voltage regulator to output a third voltage, an electronic load, a first switch between the first voltage regulator and the electronic load, a second switch between the second voltage regulator and the electronic load, and a third switch between the third voltage regulator and the electronic load. And, a method for power supply mode switching includes supplying power to an electronic load with a first voltage; switching to a second voltage; maintaining coupling of the electronic load with the second voltage while a voltage across the electronic load is less than a reference voltage; and switching to a third voltage when the voltage is greater than or equal to the reference voltage and the third voltage is less than the second voltage.
