Abstract
A controller for use in a power converter includes a comparator configured to compare a sense signal representative of an amount of energy delivered to an output of the power converter, to a target value. An update clock generator configured to receive the sense signal and to generate a clock signal having a clock frequency in response to the sense signal. A request control coupled to the comparator and to the update clock generator, the request control configured to generate a request signal having a request frequency that is responsive to an output of the comparator and that controls an operational state of a power switch of the power converter. The request control further configured to update a rate at which the request frequency of the request signal is responsive to the clock frequency of the clock signal.
