3 Description
The UC1846/7 family of control devices provides all of the necessary features to implement fixedfrequency, current-mode control schemes while maintaining a minimum external parts count. The superior performance of this technique can be measured in improved line regulation, enhanced load response characteristics, and a simpler, easier-todesign control loop. Topological advantages include inherent pulse-by-pulse...
