FEATURES  
DESCRIPTION  
Automatic Feed Forward Compensation  
The UC1846/7 family of control ICs provides all of the necessary  
features to implement fixed frequency, current mode control  
schemes while maintaining a minimum external parts count. The su-  
perior performance of this technique can be measured in improved  
line regulation, enhanced load response characteristics, and a sim-  
pler, easier-to-design control loop. Topological advantages include  
inherent pulse-by-pulse current limiting capability, automatic sym-  
metry correction for push-pull converters, and the ability to parallel  
“power modules" while maintaining equal current sharing.  
Programmable Pulse-by-Pulse Current  
Limiting  
Automatic Symmetry Correction in Push-pull  
Configuration  
Enhanced Load Response Characteristics  
Parallel Operation Capability for Modular  
Power Systems  
Protection circuitry includes built-in under-voltage lockout and pro-  
grammable current limit in addition to soft start capability. A shut-  
down function is also available which can initiate either a complete  
shutdown with automatic restart or latch the supply off.  
Differential Current Sense Amplifier with  
Wide Common Mode Range  
Double Pulse Suppression  
500mA (Peak) Totem-pole Outputs  
±1% Bandgap Reference  
Under-voltage Lockout  
Soft Start Capability  
Other features include fully latched operation, double pulse sup-  
pression, deadline adjust capability, and a ±1% trimmed bandgap  
reference.  
The UC1846 features low outputs in the OFF state, while the  
UC1847 features high outputs in the OFF state.
