<P>PROBLEM TO BE SOLVED: To provide techniques for controlling output power from a switching power supply. <P>SOLUTION: A switching regulator comprises a switch to be coupled to an energy transfer element of a power supply. A controller is coupled to the switch to control a switching of the switch to regulate an output voltage and an output current at an output of power supply output. A feedback circuit is coupled to the controller. The feedback circuit receives a feedback signal from the output of the power supply. Combinations of the output voltage and the output current correspond to output regions. There is at least one regulated output region and one unregulated output region. At least one unregulated output region is a self-protection auto-restart region. Within at least one unregulated output region, the switching regulator provides continuous output power at substantially the maximum output power of the switching regulator. Each output region corresponds to a magnitude and duration of the feedback signal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
