Abstract
A switching regulator () includes a sense resistor (Rs), a sense current generating circuit () for generating a sense current (Isense) commensurate with a sense voltage (Vsense), a slope current generating circuit () for generating a slope current (Islope) with a ramped or triangular waveform, a slope voltage generating circuit () for generating a slope voltage (Vslope) commensurate with a summed current (Isense plus Islope), an error amplifier (ERR) for generating an error voltage (Verr) commensurate with an error of an output, a comparator (CMP) for comparing the error voltage (Verr) with the slope voltage (Vslope) to generate a PWM signal and a switching control section (CTRL) for turning on and off an output transistor (N) based on the PWM signal.
