Features - 1 Automatic Feedforward pensation - Programmable Pulse-by-Pulse Current Limiting - Automatic Symmetry Correction in Push-Pull Configuration - Enhanced Load Response Characteristics - Parallel Operation Capability for Modular Power Systems - Differential Current Sense Amplifier with Wide mon Mode Range - Double-Pulse Suppression - 500-m A (Peak) Totem-pole Outputs - ±1% Band Gap Reference - Undervoltage Lockout - Soft-Start Capability - Shutdown Terminal - 500-k Hz Operation 2 Applications - Telemunication Power Converters - Industrial Power Converters 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...
