UC3847N

UC3847N Description
The UC3847N family of control devices 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 improved line regulation, enhanced load response characteristics, and a simpler, easier-to-design control loop. Topological advantages include inherent pulse-by-pulse current limiting capability automatic symmetry correction for push-pull converters, and the ability to parallel power modules while maintaining equal current sharing.
