HIGH PERFORMANCE  
CURRENT MODE  
CONTROLLERS  
The UC3842B, UC3843B series are high performance fixed frequency  
current mode controllers. They are specifically designed for Off–Line and  
dc–to–dc converter applications offering the designer a cost–effective  
solution with minimal 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 totem pole output ideally suited for driving a  
power MOSFET.  
N SUFFIX  
Also included are protective features consisting of input and reference  
undervoltage lockouts each with hysteresis, cycle–by–cycle current limiting,  
programmable output deadtime, and a latch for single pulse metering.  
These devices are available in an 8–pin dual–in–line and surface mount  
(SO–8) plastic package as well as the 14–pin plastic surface mount (SO–14).  
The SO–14 package has separate power and ground pins for the totem pole  
output stage.

The UCX842B has UVLO thresholds of 16 V (on) and 10 V (off), ideally  
suited for off–line converters. The UCX843B is tailored for lower voltage  
applications having UVLO thresholds of 8.5 V (on) and 7.6 V (off).
