KA3882/3/4/5  
SMPS CONTROLLER  
CURRENT MODE PWM CONTROLLER  
8 DIP  
The KA3882/3/4/5 are fixed PWM controller for Off-Line and DC  
to DC converter applications. The internal circuits include UVLO,  
low start up current circuit, temperature compensated reference,  
high gain error amplifier, current sensing comparator, and high  
current totempole output for driving a POWER MOSFET. Also KA  
3882/3/4/5 provide low start up current below 0.3mA and short  
shutdown delay time typ. 100ns.  
The KA3882 and KA3884 have UVLO threshold of 1 6V(on) and  
10V(off).  
8 SOP  
The KA3883 and KA3885 are 8.4V(on) and 7.6V(off).  
The KA3882 and KA3883 can operate within 100% duty cycle.  
The KA3884 and KA3885 within 50% by using T Flip-Flop.  
FEATURES  
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 Totempole Output  
Output Swing Limiting: 22V
