CONTROLLER  
DIP-16  
DESCRIPTION  
The UTC UC3846 control IC offers all necessary features for  
accomplishment of fixed frequency, current mode control functions,  
however it contains the least external parts. The performance of this  
technique is superior to the others in better line regulation,  
enhanced load response characteristics while designing a simpler  
and easier control loop for design. It owns topological advantages of  
inherent pulse-by-pulse current limiting, automatic symmetry  
correction for push-pull converters, and the ability to parallel “power  
modules" for equal current sharing.  
SOP-16  
SOP-16W  
Protection loop includes soft start, built-in under-voltage lockout  
and programmable current limit. The shutdown circuitry can  
provide either a complete shutdown with automatic restart or the  
supply off-latch.  
In addition, many other features can also be available, including  
fully latched operation, double pulse suppression, deadline adjust,  
and a ±1% trimmed bandgap reference.  
The UTC UC3846 features low outputs in the OFF state.
