Title:
スイッチング電源における障害条件に対する条件付き応答のための方法および装置
Document Type and Number:
Japanese Patent JP4987370
Kind Code:
B2
Abstract:
Techniques are disclosed to regulate an output of a power converter. One example power converter includes an energy element (130) coupled between an input and an output of the power converter. A switch (125) included in the power converter is coupled to the input of the energy transfer element (130). The power converter also includes a controller circuit (175) coupled to the switch (125). The controller circuit (175) is also coupled to receive a feedback signal (170) representative of the output of the power converter and coupled to receive a signal representative of the power converter input voltage. The controller circuit (175) is coupled to control switching of the switch (125) to provide a regulated output parameter at the output of the power converter in response to the feedback signal (170). The controller circuit (175) is coupled to latch the power converter into an off state in response to a detection of a loss of regulation of a power converter output parameter if the power converter input voltage is above a threshold level. The controller circuit (175) is also unresponsive to the signal representative of the power converter input voltage while the power converter output parameter is in regulation.
