Abstract:
In a described example, a method includes using a power supply, supplying an output voltage that varies in response to a reference voltage; detecting a voltage ramp in an input reference voltage; generating an offset voltage waveform; adding the offset voltage waveform to the input reference voltage to generate a second reference voltage; and using the second reference voltage, operating the power supply to supply the output voltage.
