Note	This datasheet PDF includes multiple part numbers: UC3843A, UC3842A. Please refer to the document for exact specifications by model.

The UC184xA family of control ICs provides all the necessary

to implement off-line fixed-frequency, current-mode switching power supplies with a minimum of external components. The current mode architecture demonstrates improved load regulation, pulse-by-pulse current limiting and inherent protection of the power supply output switch. The IC includes: A bandgap reference trimmed to ±1% accuracy, an error amplifier, a current sense comparator with internal clamp to 1V, a high current totem pole output stage for fast switching of power MOSFET's, and an ext.
