Patent ID: 7378827

Claim:
A switching regulator for supplying a regulated output voltage to a load circuit in response to an applied direct current (DC) input voltage, the switching regulator comprising; an error amplifier circuit including a comparator for generating an amplifier control signal in response to a portion of the regulated output voltage and a predetermined reference voltage, and an output stage for generating an amplifier output signal in response to the control signal and the applied DC input voltage; and an analog voltage ramp circuit including: a current source for generating a first current; a current divider for generating a second current in response to the first current, wherein the second current is lower than the first current; an integrator circuit for generating a ramp voltage signal in response to the second current; and an analog voltage clamp circuit for clamping the amplifier control signal to the ramp voltage signal until the ramp voltage signal increases to a final voltage level.
