Abstract:
A switched-mode power supply device includes a power switch configured to transfer power from a supply line to a load in switched-mode; a first oscillator configured to operate at a frequency proportional to a voltage of the supply line; a second oscillator configured to operate at a frequency proportional to a voltage of the load; and a regulator configured to operate the power switch according to a duty cycle based on a ratio between the first and second oscillator frequencies.
