LOW LOSS POWER CONVERTER CONTROL

A voltage output circuit and methods for operating voltage output circuits are disclosed. In some embodiments, a voltage output circuit comprises a power converter and a power converter controller, and is configured to provide a desired output voltage for charging an output. In some embodiments, the power converter comprises a first transistor and a second transistor. By using the power converter controller to control the power converter, a current through the first transistor may be increased until it reaches a value corresponding to the desired output voltage. When the value is reached, the first transistor may be turned off to cause a drain-to-source voltage of the second transistor to become zero. When the drain-to-source voltage of the second transistor becomes zero, the second transistor turns on, and an output of the power converter is charged to the desired output voltage.
