Abstract
A controller for a DC/DC converter includes multiple signal generators and a control circuit. The signal generators generate multiple pulse signals, each signal generator generating a corresponding pulse signal of the pulse signals and controlling the corresponding pulse signal to have a predetermined pulse width by counting a same preset number of cycles of a same oscillating signal. The control circuit selectively activates the signal generators according to an output of the DC/DC converter to generate the pulse signals.
