KA3882C/KA3883C  
SMPS Controller  
Features  
Description  
• Low Start Current 0.2mA (Typ)  
• Operating Range Up To 500kHz  
• Cycle by Cycle Current Limiting  
• Under Voltage Lock Out With Hysteresis  
• Short Shutdown Delay Time: Typ.100ns  
• High Current Totem-Pole Output  
• Output Swing Limiting: 22V  
The KA3882C/KA3883C is a fixed PWM controller for Off  
Line and DC to DC converter applications. The internal  
circuits include an UVLO, a low start up current circuit, a  
temperature compensated reference, a high gain error  
amplifier, a current sensing comparator, and the high current  
totem-pole output for driving a POWER MOSFET. Also the  
KA3882C/KA3883C provides low start-up current below  
0.3mA and short shutdown delay time typ. 100ns. The  
KA3882C has the UVLO threshold of 16V (on) and  
10V(off). The KA3883C is 8.4V(on) and 7.6V(off). The  
KA3882C and KA3883C can operate within 100% duty  
cycle.
