FEATURES
Automatic Feed Forward Compensation
DESCRIPTION
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 su-
Limiting
perior performance of this technique can be measured in improved
Automatic Symmetry Correction in Push-pull line regulation, enhanced load response characteristics, and a sim-

pler, easier-to-design control loop. Topological advantages include
inherent pulse-by-pulse current limiting capability, automatic sym-
Enhanced 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.
Power Systems
Protection circuitry includes built-in under-voltage lockout and pro-
Differential Current Sense Amplifier with
grammable current limit in addition to soft start capability. A shut-
Wide Common Mode Range
down function is also available which can initiate either a complete
shutdown with automatic restart or latch the supply off.
