KA3842AC/KA3842AE  
SMPS Controller  
Features  
Description  
„ Low start current 0.2mA (Typ.)  
„ Operating range up to 500kHz  
„ Cycle by cycle current limiting  
The KA3842AC/KA3842AE are fixed PWM controllers  
for Off Line and DC to DC converter applications. The  
internal circuits include UVLO, low start up current, tem-  
perature compensated reference, high gain error ampli-  
fier, current sensing comparator, and high current totem  
pole output for driving a POWER MOSFET. Also  
KA3842AC/KA3842AE provides low start up current  
below 0.3mA and short shutdown delay time, typically  
100ns. The KA3842AC/KA3842AE has a UVLO thresh-  
old of 16V(on) and 10V(off). The KA3842AC/KA3842AE  
can operate within a 100% duty cycle.  
„ Under Voltage Lock Out (UVLO) with hysteresis  
„ Short shutdown delay time: Typ.100ns  
„ High current totem-pole output  
„ Output swing limiting: 22V
