ABSTRACT:
There is provided a DC-DC converter control circuit, wherein a reference feedback signal related to a supply voltage to a load is compared to a reference oscillation signal to generate a result of comparison. The result of comparison is used as a switching control signal to control the supply voltage to the load. The result of comparison is frequency divided to generate a frequency divided signal; and the switching control signal is generated in response to the frequency divided signal.
