Abstract
A switching regulator circuit with improved slope compensation for providing a regulated voltage to a load. The regulator circuit includes a power source and a switch circuit configured to control the coupling of the power source to the load. The operation of the switch circuit is controlled by a control signal generated by a control circuit. A feedback circuit is provided for generating a feedback signal indicative of the regulated voltage provided by the switching regulator circuit to the load. A circuit is provided to generate a sensed signal indicative of the current supplied by the power source. The regulator circuit further includes a timing signal generator for generating a timing signal, a ramp signal generator for generating a ramp signal, and a current source controlled by the ramp signal for generating a compensation signal indicative of the ramp signal. The control circuit generates the control signal based on the compensation signal, the timing signal, the sensed signal and the feedback signal.
