Abstract:
1. A system for analyzing an operation of a switching power converter, comprising: a digital controller for receiving an analog signal representing the output DC voltage of the power converter for comparison to a desired output voltage level and generating switching control signals to control the operation of the switching power converter to regulate the output DC voltage to said desired output voltage level, the digital controller including at least one portion of a control loop of the digital controller, the at least one portion of the control loop generating a signal in a first mode of operation; a microcontroller for emulating an operation of the at least one portion of the control loop during a second mode of operation and generating a synthesized version of the original signal; and wherein the at least one portion of the control loop of the digital controller is switched into the control loop in a first mode of operation and the microcontroller is switched into the control loop in the second mode of operation to perform the operation of the at least one portion of the control loop.
