Abstract

An error amplifier receives an on/off signal and supplies an error signal to an integrator. The latter provides a ramp output, which is fed back to the error amplifier whereby the error signal therefrom further is dependent upon the ramp output. The error signal is selectively clamped positively and negatively whereby the resulting ramp output has a constant ramp time, with no ramp on/off delay.
