Power supply controller having analog to digital converter |
摘要 |
A power supply control method of performing a feedback control of an output voltage based on a deviation signal for a standard voltage value serving as a target value for the output voltage and a digital signal generated by analog/digital (A/D) conversion of the output voltage, the method includes selecting a range of the reference voltage for the A/D conversion based on the digital signal in a power supply startup period, and selecting a range of the reference voltage for the A/D conversion based on the deviation signal or a signal corresponding to the deviation signal in a steady state period.
