Claim Text:
1. A controller for controlling a DC to DC converter, comprising: a modulator circuit operative to provide at least one pulse width modulated switching control signal at least partially according to a clock signal in a plurality of converter switching cycles to selectively activate and deactivate at least one converter switching device to control an output voltage of the DC to DC converter; an error amplifier circuit including a first input operative to receive a reference signal representing a desired output voltage for the DC to DC converter, a second input operative to receive a feedback signal representing the output voltage of the DC to DC converter, and an error amplifier output operative to provide an error signal based on a comparison of the reference signal with the feedback signal; a summation circuit including a first input operative to receive a current sense signal representing a current flowing in the DC to DC converter, a second input operative to receive a slope compensation ramp signal, and an output operative to provide a compensated current sense signal based on a summation of the current sense signal and the slope compensation ramp signal; and a compensation circuit, comprising:
