The disclosed DC-to-DC converter circuit comprises a tracking ADC configured to drive a DC-to-DC converter. In particular, the tracking ADC is configured to receive an analog feedback voltage from the output of the DC-to-DC converter. The analog feedback voltage is compared to an analog reference voltage and based upon the comparison a digital ADC output signal, comprising a digital code, is generated to drive the DC-to-DC converter. The digital ADC output signal is received by the DC-to-DC converter, which is configured to compare the digital code to a target code value. Based upon this comparison, the digital signal drives operation of the DC-to-DC converter by indicating whether the output of the DC-to-DC converter will be adjusted (e.g., by telling the DC-to-DC converter to increase its output voltage, to decrease its output voltage, or to keep its output voltage the same). Other systems and methods are also disclosed. |
