PRINCIPLES OF OPERATION AND TYPICAL CHARAC- turn-off signal to the outputs; and a 150µA-current sink  
TERISTIC SHUTDOWN OPTIONS

begins to discharge the external soft-start capacitor. If the  
shutdown command is short, the PWM signal is termi-  
nated without significant discharge of the soft-start ca-  
Since both the compensation and soft-start terminals  
(Pins 9 and 8) have current source pull-ups, either can  
readily accept a pull-down signal which only has to sink a  
maximum of 100µA to turn off the outputs. This is subject  
to the added requirement of discharging whatever exter-  
nal capacitance may be attached to these pins.  
pacitor, thus, allowing, for example,  
a convenient  
implementation of pulse-by-pulse current limiting. Holding  
Pin 10 high for a longer duration, however, will ultimately  
discharge this external capacitor, recycling slow turn-on  
upon release.  
Pin 10 should not be left floating as noise pickup could  
conceivably interrupt normal operation. All transitions of  
the voltage on pin 10 should be within the time frame of  
one clock cycle and not repeated at a frequency higher  
than 10 clock cycles.  
An alternate approach is the use of the shutdown circuitry  
of Pin 10 which has been improved to enhance the avail-  
able shutdown options. Activating this circuit by applying  
a positive signal on Pin 10 performs two functions; the  
PWM latch is immediately set providing the fastest
