DESCRIPTION  
The UTC UC3842B/3843B are specifically designed for off-line  
and dc-to-dc converter applications offering the designer a  
cost-effective solution with minimal external components.  
The UC3842B has UVLO thresholds 16V (on) and 10V(off),  
ideally suited for off-line converters. The UC3843B is tailored for  
lower voltage applications having UVLO thresholds of 8.4V(on)  
and 7.6V(off).
