A switching regulator includes a compensation circuit for applying a scaling
factor
to the loop gain of the feedback control loop of the regulator. In operation, the
loop gain of the feedback control loop has a dependency on the input and output
voltages of the switching regulator. The compensation circuit applies a function
as the scaling factor where the function is a reciprocal function of the loop gain
dependency on the input voltage and output voltage. In one embodiment, the loop
gain has a dependency on the ratio VIN/VOUT and a scaling
factor having a value indicative of the ratio VOUT/VIN is
applied by the compensation circuit. In one embodiment, the compensation circuit
is coupled in series with the output circuit of an error amplifier in the feedback
control loop of the regulator. In another embodiment, the compensation circuit
is subsumed within the circuitry of the error amplifier.
