Claim:
1. A power supply providing an output voltage, the power supply comprising: an error amplifier controlling the power supply based on comparing a reference voltage with a feedback voltage representative of the output voltage; a digital to analog converter (DAC) coupled to the error amplifier, the DAC providing the reference voltage to the error amplifier; and a control circuit providing a digital voltage code to the DAC, the DAC converting the digital voltage code into the reference voltage, wherein the control circuit adds an offset count value to the digital voltage code when the digital voltage code begins transitioning from a present voltage code value to a new voltage code value, wherein the combined offset count value and digital voltage code is provided to the DAC, wherein the control circuit decrements the offset count value to zero when the output voltage reaches a new value corresponding to the new voltage code value.
