Abstract
A switching power converter converts an input DC voltage to an output DC voltage using a switch to selectively connect an input DC voltage energy source. A switching controller controls the switch. A pulse width modulation centering signal is generated by a spread spectrum clock signal generator. An error amplifier of the switching controller generates an analog error signal based on a switching voltage measured after the switching of the switching power converter, the output voltage of the switching power converter, the pulse width modulation centering signal and a reference. A pulse width modulated signal generator generates the pulse width modulation signal to control the switch of the switching power converter based on the pulse width modulation centering signal and the analog error signal.
