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
- Qualified and PPAP Capable
