UC3842/UC3843/UC3844/UC3845  
SMPS Controller  
Features  
Description  
• Low Start Up Current  
The UC3842/UC3843/UC3844/UC3845 are fixed  
• Maximum Duty Clamp  
frequency current-mode PWM controller. They are  
• UVLO With Hysteresis  
• Operating Frequency Up To 500KHz  
specially 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. TheUC3842 and  
UC3844 have UVLO thresholds of 16V (on) and 10V (off)  
The UC3843 and UC3845 are 8.5V (on) and 7.9V (off) The  
UC3842 and UC3843 can operate within 100% duty cycle.  
The UC3844and UC3845 can operate with 50% duty cycle.
