Patent number: 9071160Abstract: A method and controller for power dependant mains under-voltage (“brown-out”) protection is disclosed. Brown-out protection is meant for protection against overheating due to low mains voltage and associated high mains current. The disclosed method and controller allow for lower mains voltages at low load by comparing the mains voltage with a signal indicating the actual power level of the power supply. In converters such as flyback converters, this brown-out protection can be implemented by comparing the actual peak voltage of the mains voltage with a control signal that indicates the power level. In other embodiments, the mains voltage is compared to a preset level by means of a comparator. Provided the voltage passes the preset level prior to opening the control window, the SMPS functions normally. Conversely, brown-out protection is initiated if the voltage does not pass the preset level before the control window opens.Type: GrantFiled: July 14, 2011Date of Patent: June 30, 2015Assignee: NXP B.V.Inventor: Frans Pansier
