Abstract
In some examples, a device for controlling a transistor in a power converter system includes a first circuit configured to generate an error current based on a difference between a reference signal and a feedback signal, where the feedback signal depends on an output voltage of the power converter system. The device also includes a frequency generator configured to generate an activation signal based on the difference between the reference signal and the feedback signal. The device further includes a pedestal circuit configured to define a peak current threshold for the transistor based on an offset value. The device also includes a logic circuit configured to activate the transistor based on the activation signal and deactivate the transistor when a current sense signal reaches the defined peak current threshold, where the current sense signal is representative of a power current conducted by the transistor.
