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 · Programmable Pulse-by-Pulse Current schemes while maintaining a minimum external parts count. The Limiting superior performance of this technique can be measured in im- · Automatic Symmetry Correction in Push-pull proved line regulation, enhanced load response characteristics, and Configuration a simpler, easier-to-design control loop. Topological advantages in- · Enhanced Load Response Characteristics clude inherent pulse-by-pulse current limiting capability, automatic symmetry correction for push-pull converters, and the ability to par- · Parallel Operation Capability for Modular allel "power modules" while maintaining equal current sharing. Power Systems Protection circuitry includes built-in under-voltage lockout and pro- · Differential Current Sense Amplifier with grammable curre
