KA3842B/KA3843B/KA3844B/KA3845B  
SMPS Controller  
Features  
Description  
• Low Start Up Current  
• Maximum Duty Clamp  
• UVLO With Hysteresis  
• Operating Frequency Up To 500KHz  
The KA3842B/KA3843B/KA3844B/KA3845B are fixed  
frequency current-mode PWM controller. They are spe-  
cially designed for Off - Line and DC-to-DC converter  
applications with minimum external components. These  
integrated circuits feature a trimmed oscillator for precise  
duty cycle control, a temperature compensated reference,  
high gain error amplifier. current sensing comparator, and a  
high current totempole output Ideally suited for driving a  
power MOSFET. Protection circuity Includes built in  
under-voltage lockout and current limiting. The KA3842B  
and KA3844B have UVLO thresholds of 16V (on) and  
10V (off) The KA3843B and KA3845B are 8.5V (on) and  
7.9V (off) The KA3842B and KA3843B can operate within  
100% duty cycle. The KA3844B and KA3845B can operate  
with 50% duty cycle.
