S3842P  
Semiconductor  
Current Mode PWM Controller  
Descriptions  
The S3842, high performance current mode controller, Provides the necessary features to  
off-line and DC-DC fixed frequency current control applications offering the designer a cost  
effective solution with minimal external components. Internally protection circuity includes  
built-in input and reference under-voltage lockout and current limiting with hysteresis.  
Also other characteristics of internal circuit provide improved line regulation, enhanced load  
response, trimmed oscillation for precise duty cycle control, a temperature compensated  
reference, high gain error amplifier, current sensing comparator and totempole output  
designed to source and sink high peak current from a capacitive load such as the gate of a  
power MOSFET.  
Features  
Optimized for off-line control  
Low start up and operating current  
Pulse by pulse current limiting  
Current mode operation to 500  
Under voltage lockout with 6V hysteresis  
Internally trimmed bandgap reference about 5V  
Enhanced load response characteristic Automatic feed forward compensation
