The UCx84x series of control integrated circuits provide the features that are necessary to implement off-line or DC-to-DC fixed-frequency current-mod.

UC2843 Features

* Optimized for off-line and DC-to-DC converters
* Low start-up current (< 1mA)
* Automatic feedforward compensation
* Pulse-by-pulse current limiting
* Enhanced load-response characteristics
* Undervoltage lockout with hysteresis
* Double-puls

UC2843 Applications

* Switching regulators of any polarity
