Abstract: Most of the AC-DC converters have an analog control loop, which costs additional pins for the compensator, and there are limited options to change settings when, for example, the output voltage needs to change. This specification discloses systems and methods, where a delta-sigma ADC (analog-to-digital converter) is used to digitize the input voltage. The filter after the delta-sigma ADC can give a big delay, which reduces the phase margin of the control loop. To minimize the delay, this invention ensures that, when the setpoint is reached, the input of the delta-sigma modulator is in the middle of the input range. In some embodiments, a digital control loop can be implemented using a delta-sigma modulator together with a PI controller (proportional-integrator controller).
