Abstract
A control signal is applied to a pulse generating circuit configured to generate pulses that are modulated in width. A circuit provides for slope-compensation of the control signal. The circuit includes a digital-to-analog converter that generates a decreasing sawtooth signal. A triggering circuit operates to trigger steps of the sawtooth signal and resetting the sawtooth signal. The sawtooth signal is reset at a cadence of a frequency of the pulses that are modulated in width.
