UC1842/3/4/5  
UC2842/3/4/5  
ERROR AMPLIFIER OPEN-LOOP  
FREQUENCY RESPONSE  
OUTPUT SATURATION CHARACTERISTICS  
OPEN-LOOP LABORATORY FIXTURE  
High peak currents associated with capacitive loads ne- single point ground. The transistor and 5k potentiometer  
cessitate careful grounding techniques. Timing and by- are used to sample the oscillator waveform and apply  
pass capacitors should be connected close to pin 5 in a an adjustable ramp to pin 3.  
SHUT DOWN TECHNIQUES  
Shutdown of the UC1842 can be accomplished by two clock cycle after the shutdown condition at pin 1 and/or  
methods; either raise pin 3 above 1V or pull pin 1 below 3 is removed. In one example, an externally latched  
a voltage two diode drops above ground. Either method shutdown may be accomplished by adding an SCR  
causes the output of the PWM comparator to be high which will be reset by cycling VCC below the lower  
(refer to block diagram). The PWM latch is reset domi- UVLO threshold. At this point the reference turns off, al-  
nant so that the output will remain low until the next lowing the SCR to reset.
