Abstract

A controller including a voltage synthesizer for a switching regulator includes a synthesizer input to be coupled to an input of the regulator. First and second replica switching transistors are connected at a first node. A resistor couples between the first node and a second node, and a capacitor couples between the second node and ground. A transconductance stage compares a voltage sampled onto the capacitor to the output voltage of the regulator and generates an output signal in response to the comparison. A first switch couples between first and second inputs of the transconductance stage. The first switch is turned on during each cycle of operation of the voltage synthesizer to reset the capacitor voltage to the output voltage of the regulator.
