Claim:
1. A voltage converter for converting an input voltage to an output voltage at an output for a load, comprising: an output controller configured to generate a control signal based on a feedback signal which indicates an output condition of the voltage converter; a power mode controller configured to generate a power mode signal different than the control signal in response to a signal independent from the feedback signal used by the output controller and which indicates the load is in a lower power mode instead of a higher power mode; and an integrated power stage comprising a plurality of switches coupled in parallel between the input voltage and the output and a driver circuit connected to the switches, the integrated power stage configured to supply power to the load responsive to the control signal and the power mode signal, the driver circuit configured to control the switches according to the control signal and disable at least one of the switches responsive to the power mode signal, regardless of the control signal.
