摘要:
A voltage regulator (10) having an undervoltage protection circuit 11 and a method for protecting against an output voltage out being less than a predetermined level. The voltage regulator has an undershoot limitation circuit (11) coupled between a feedback network (30) and a regulation section (42). A power factor correction circuit (46) is connected to the regulatio section. An output voltage out from the power factor correction circuit (46) is fed back to the feedback network (30), which transmits a portion of the output voltage to the undershoot limitation circuit (11). If the output voltage is greater than the predetermined voltage level, a switching circuit portion (34) of the undershoot limitation circuit (11) transmits a normal control signal to the regulation circuit (42). If the output voltage is less than the predetermined voltage level, the switching circuit portion transmits an enhanced control signal to the regulation circuit. The enhanced control signal quickly brings the output voltage up to at least the minimum desired level.

具有欠压保护电路11的电压调节器(10)和防止输出电压输出小于预定电平的方法。 电压调节器具有耦合在反馈网络(30)和调节部分(42)之间的下冲限制电路(11)。 功率因数校正电路(46)连接到调节部分。 从功率因数校正电路(46)输出的输出电压被反馈到反馈网络(30),反馈网络将输出电压的一部分传送到下冲限制电路(11)。 如果输出电压大于预定电压电平,则下冲限制电路(11)的开关电路部分(34)将正常控制信号发送到调节电路(42)。 如果输出电压小于预定电压电平,则开关电路部分向调节电路发送增强的控制信号。 增强的控制信号快速使输出电压达到至少最小期望水平。
