Abstract
Apparatus for use in a system, including a microcontroller for controlling the system, where the microcontroller includes at least one internal module capable of generating a periodic pulse signal. The microcontroller is programmed and operated so that the internal module generates a periodic pulse signal that is a pseudo-random spread spectrum oscillator signal. A switching mode power supply is responsive to the pseudo-random spread spectrum oscillator signal. The switching mode power supply comprises a solid state switch and a modulator for driving the solid state switch with a drive signal related to the periodic pulse signal generated by the internal module of the microcontroller.
