Current Mode PWM Controller  
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  
superior performance of this technique can be measured in im-  
proved line regulation, enhanced load response characteristics, and  
a simpler, easier-to-design control loop. Topological advantages in-  
clude inherent pulse-by-pulse current limiting capability, automatic  
symmetry correction for push-pull converters, and the ability to par-  
allel “power modules" while maintaining equal current sharing.

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.
