The UC1846/7 family of control ICs provides all of the necessary features to implement fixed frequency, current mode control Programmable Pulse-by-Pulse Current schemes while maintaining a minimum external parts count. The suLimiting perior performance of this technique can be measured in improved Automatic Symmetry Correction in Push-pull line regulation, enhanced load response characteristics, and a simConfiguration pler, easier-to-design control loop. Topological advantages include inherent pulse-by-pulse current limiting capability, automatic symEnhanced Load Response Characteristics metry correction for push-pull converters, and the ability to parallel Parallel Operation Capability for Modular "power modules" while maintaining equal current sharing.
