  • Power supply with low to high power transition mode
    Patent number: 10014774
    Abstract: One example includes a switching power supply. The switching power supply includes a power stage, a feedback loop, and a simulated feedback error generator. The power stage provides an output signal in response to a switching signal. The feedback loop monitors the output signal and provides a feedback error signal to adjust the switching signal to regulate the output signal. The simulated feedback error generator temporarily provides a simulated feedback error signal during a transition period from the low power mode to a high power mode of the switching power supply until the feedback loop has enough time to provide the feedback error signal.
