Abstract
Methods and apparatus for a power supply according various aspects of the present invention operate in conjunction with a voltage converter for converting an input voltage to an output voltage. For example, the converter may comprise an output controller configured to generate a control signal, a power mode controller, and an integrated power stage. The power stage may include a multiple switch segments coupled in parallel between the input voltage and the output, and a driver circuit responsive to the output controller and the power mode controller and connected to the switch segments. The driver circuit controls the switch segments according to the control signal to activate the switch segments in the switch circuit. The driver circuit also disables one or more of the switch segments according to the power mode signal to permit reduced power delivery and demand states.
