Either method caused the output of PWM comparator to be high(refer to block diagram).The PWM latch is reset dominant so that the output will remain low until the next clock cycle after the shutdown condition at pins 1 and/or 3 is removed . In one example, an externally latched shut –down may be accomplished by adding an SCR which be reset by cycling Vcc below the lower UVLO threshold.

LM431Adjustable Precision Zener Shunt RegulatorGeneral DescriptionThe LM431is a 3-terminal adjustable shunt regulator with guaranteed temperature stability over the entire temperature range of operation.It is now available in a chip sized pack-age (4-Bump micro SMD)using National’s micro SMD pack-age technology.The output voltage may be set at any level greater than 2.5V (V REF )up to 36V merely by selecting two external resistors that act as a voltage divided network.Due to the sharp turn-on characteristics this device is an excel-lent replacement for many zener diode applications.Featuresn Average temperature coefficient 50ppm/˚Cn Temperature compensated for operation over the full temperature rangen Programmable output voltage n Fast turn-on response n Low output

在一些特殊的应用中，也可平行于内部负反馈电阻外接阻容元件来进行增益和频响调整。例如，我们可以通过提升负反馈频响网络以补偿扬声器低频段灵敏度低的缺点，它可以通过在1脚和5脚之间(平行于内部15KΩ电阻)接一个RC串联网络来实现。对于6dB的有效低频提升来说：R≈15KΩ，当8脚开路时，能保证稳定工作的R最小值为 R=10KΩ，如果1脚和8脚之间有旁路电容，则R的最小值降为R=2KΩ，有这项限制的原因为放大器内部补偿仅至闭

Either method caused the output of PWM comparator to be high(refer to block diagram).The PWM latch is reset dominant so that the output will remain low until the next clock cycle after the shutdown condition at pins 1 and/or 3 is removed . In one example, an externally latched shut –down may be accomplished by adding an SCR which be reset by cycling Vcc below the lower UVLO threshold. At this point the reference turns off allowing the SCR to reset.UTC UC3842A / 3843A LINEAR INTEGRATED CIRCUITUTC UNISONIC TECHNOLOGIES CO.
