Product Description

High Performance Current Mode Controllers
The UC3844B, UC3845B series are high performance fixed frequency current mode controllers. They are specifically designed for Off−Line and dc−dc converter applications offering the designer a cost−effective solution with minimal external components. These integrated circuits feature an oscillator, a temperaturecompensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.
Features
•Trimmed Oscillator for Precise Frequency Control
•Oscillator Frequency Guaranteed at 250 kHz
•Current Mode Operation to 500 kHz Output Switching Frequency
•Output Deadtime Adjustable from 50% to 70%
•Automatic Feed Forward Compensation
•Latching PWM for Cycle−By−Cycle Current Limiting
•Internally Trimmed Reference with Undervoltage Lockout
•High Current Totem Pole Output
•Undervoltage Lockout with Hysteresis
•Low Startup and Operating Current
•These Devices are Pb−Free and are RoHS Compliant
•NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100
