Abstract
A power supply includes a storage component to store an output current value representative of a magnitude of output current supplied by an output voltage of a power converter to power a load. The power supply further includes an offset reference generator and a controller. The offset reference generator produces an offset reference signal, the output current value being offset by the offset reference signal. The controller controls generation of the output voltage of the power converter as a function of the offset output current value with respect to a threshold signal (value). Additionally, the controller is configured to detect a startup mode of a power converter operative to convert an input voltage into an output voltage. During the startup mode, the controller: i) produces a threshold signal having a magnitude that varies over time, and ii) controls operation of switches in the power converter as a function of the threshold signal while the power converter is operated in a diode emulation mode. Implementation of the startup mode monotonically increases a magnitude of the output voltage without dips.
