Abstract:
An exemplary embodiment of an alternating valley switching controller is provided. The alternating valley switching controller includes a valley detection circuit and an alternating circuit. The valley detection circuit is coupled to an auxiliary winding of a transformer to generate a valley-detection signal. The alternating circuit alternates a plurality of switching periods of a switching signal according to a blanking-window signal and the valley-detection signal. The blanking-window signal switches between a first voltage level and a second voltage level in the plurality of switching periods. The plurality of switching periods includes at least two first periods and at least two second periods which occur alternately in response to the first voltage level and the second voltage of the blanking-window signal.

Claim (Index 11):
A switching controller for a power supply comprising:\n an alternating circuit configured to form a switching signal to switch a transformer to regulate an output voltage of the power supply, the switching signal having a plurality of switching periods wherein each period has an on-time and an-off time; a detection circuit configured to receive a valley signal that is representative of oscillations of the transformer during one or more off-times of the switching signal, the oscillations of each off-time having peaks and valleys, the detection circuit configured to generate a valley-detection signal in response to detecting one or more valleys of the oscillations; the alternating circuit configured to form a first switching period and to detect a first number of valleys of the oscillations during the first switching period, the alternating circuit configured to terminate the first switching period and initiate an immediate subsequent second switching period in response to detecting the first number of valleys, the alternating circuit configured to terminate the second switching period and to initiate an immediately preceding third switching period in response to detecting a second number of valleys during the second switching period wherein the second number is either one number less or one number more than the first number; and the alternating circuit configured to sequentially repeat a sequence of terminating one switching period in response to detecting the first number of valleys and to terminate another switching period, that is immediately subsequent to the one switching period, in response to detecting the second number of valleys.
