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.
Features
* Optimized for off-line and DC-to-DC converters
* Low start-up current (< 1 mA)
* Automatic feedforward compensation
* Pulse-by-pulse current limiting
* Enhanced load-response characteristics
* Undervoltage lockout with hysteresis
* Double-pul
Applications
* Switching regulators of any polarity
