Abstract

A switching converter can provide an output voltage for a subsystem. A successive approximation analog to digital converter (ADC) can receive an error input based on a difference between the output voltage and a target voltage for the subsystem. The ADC can utilize a successive approximation register (SAR) and a charge scaling digital to analog converter (DAC) to generate a digital output representing the error input to adjust the switching converter. An offset controller can provide an offset value to the ADC to counter an offset error in the power management system. The ADC can alternate between utilizing the offset value and utilizing an output of the SAR to generate the digital output. Further, a range controller can adjust a voltage range, utilized by the ADC to generate the digital output, based on the error input. Other aspects are also described and claimed.
