Shutdown
Shutdown
accomplished by two methods; either raise pin 3
above 1V or pull Pin 1 below a voltage two diode
drops above ground. 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
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.
