* Optimized for off-line and DC-to-DC converters
* Low start-up current (< 1mA)
* Automatic feedforward compensation
* Pulse-by-pulse current limiting

* Switching regulators of any polarity
* Transformer-coupled DC-DC converters 3 Description The UCx84x series of.

The UCx84x series of control integrated circuits provide the features that are necessary to implement off-line or DC-to-DC fixed-frequency current-mode control schemes, with a minimum number of external components. The internally implemented circuits.
