DESCRIPTION
The SG1846 family of control ICs 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.

FEATURES
• Automatic feed forward compensation
• Programmable pulse by pulse current limiting
• Automatic symmetry correction in push-pull configuration
