High Performance  
Current Mode Controllers  
http://onsemi.com  
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.

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.  
SO–8  
D1 SUFFIX  
CASE 751

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).
