Regulated switching converter
Abstract:
A regulated switching converter having improved closed loop settling time is disclosed. An error amplifier having a voltage reference input, a feedback input, and an error output is included. An output filter having a voltage output terminal coupled to the feedback input provides an output voltage sample to the error amplifier. A compensation network coupled between the feedback input and the error output of the error amplifier includes at least one capacitor and at least one switch that is communicatively coupled across the at least one capacitor. A controller is adapted to monitor current flowing through the switching output terminal. The controller has at least one switch control output coupled to a control input of the at least one switch to allow the controller to momentarily close the at least one switch to substantially discharge the at least one capacitor when a predetermined high current state is reached.
