Abstract
A circuit for controlling a switching regulator is provided. The circuit includes a first input to receive a feedback signal from the switching regulator proportional to an output voltage of the switching regulator, a second input to receive a voltage reference signal, an output to be coupled to an input of the switching regulator, an error amplifier having a first input terminal coupled to the first input to receive the feedback signal, a second input terminal coupled to the second input to receive the voltage reference signal, and an output terminal coupled to the output, and a compensation network coupled between the second input and the output. The compensation network includes a series combination of a first capacitance and a first resistance coupled between the second input and a node, a second resistance coupled between the node and the output, and a second capacitance coupled to the node.
