    • A power supply with an open-loop protection according to the present invention comprises a transformer, a switch, a signal generation circuit, a feedback detection circuit, a brown-out detection circuit, and a delay circuit. The transformer receives an input voltage. The switch is coupled to the transformer for switching the transformer. The signal generation circuit generates a switching signal to control the switch. The feedback detection circuit generates a pull-high signal in response to a feedback signal of the power supply. The brown-out detection circuit generates a delay signal in response to the pull-high signal and the input voltage. The delay circuit counts a delay time in response to the delay signal for generating a disabling signal coupled to the signal generation circuit to latch the switching signal. The brown-out detection circuit is utilized to detect whether the input voltage is in the brown-out condition for determining whether the open-loop protection is executed.
    • 根据本发明的具有开环保护的电源包括变压器,开关,信号发生电路,反馈检测电路,欠压检测电路和延迟电路。 变压器接收输入电压。 开关耦合到变压器以切换变压器。 信号发生电路产生开关信号以控制开关。 反馈检测电路响应于电源的反馈信号产生拉高信号。 欠压检测电路响应于上拉电阻和输入电压产生延迟信号。 延迟电路响应于用于产生耦合到信号发生电路的禁用信号的延迟信号来计数延迟时间以锁存开关信号。 欠压检测电路用于检测输入电压是否处于用于确定是否执行开环保护的欠压状态。
