The UC1846/7 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 su-
perior performance of this technique can be measured in improved
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-
metry correction for push-pull converters, and the ability to parallel
“power modules" while maintaining equal current sharing.
Protection circuitry includes built-in under-voltage lockout and pro-
grammable current limit in addition to soft start capability. A shut-
down function is also available which can initiate either a complete
shutdown with automatic restart or latch the supply off.
Other features include fully latched operation, double pulse sup-
pression, deadline adjust capability, and a
±1% trimmed bandgap
reference.
The UC1846 features low outputs in the OFF state, while the
UC1847 features high outputs in the OFF state.
