Abstract
A control circuitry can be configured to receive an error signal indicating a difference between an output voltage of the power supply and a desired setpoint for the output voltage. According to one configuration, depending on the error signal, the control circuitry initiates switching between operating the control circuitry in a pulse width modulation mode and operating the control circuitry in a pulse frequency modulation mode to produce an output voltage. Operation of the control circuitry in the pulse frequency modulation mode during a transient condition, such as when a dynamic load instantaneously requires a different amount of current, enables the power supply to satisfy current consumption by the dynamic load. Subsequent to the transient condition, the control circuitry switches back to operation in the pulse width modulation mode.
