Abstract
In one embodiment, a power converter system includes a switching circuitry having a plurality of switches operable to be turned on and off to cause current to flow to deliver power to a load. A driver circuitry is responsive to an oscillation signal and generates control signals for turning on and off the switches in the switching circuitry. A free-running oscillator circuitry provides the oscillation signal to the driver circuitry. The free-running oscillator circuitry has an operational amplifier. A frequency of the oscillation signal will be higher if the operational amplifier outputs a first value, and the frequency of the oscillation signal will be lower if the operational amplifier outputs a second value.
