High Performance  
Current Mode Controllers  
The UC3844B, UC3845B series are high performance fixed  
frequency current mode controllers. They are specifically designed for  
Off−Line and dc−dc converter applications offering the designer a  
cost−effective solution with minimal external components. These  
integrated circuits feature an oscillator, 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, a latch for single pulse metering, and a flip−flop  
which blanks the output off every other oscillator cycle, allowing  
output deadtimes to be programmed from 50% to 70%.

These devices are available in an 8−pin dual−in−line and surface  
mount (SOIC−8) plastic package as well as the 14−pin plastic surface  
mount (SOIC−14). The SOIC−14 package has separate power and  
ground pins for the totem pole output stage.  
The UCX844B has UVLO thresholds of 16 V (on) and 10 V (off),  
ideally suited for off−line converters. The UCX845B is tailored for  
lower voltage applications having UVLO thresholds of 8.5 V (on) and  
7.6 V (off).
