High Performance Current Mode Controllers
The UC3844, UC3845 series are high performance fixed frequency current mode controllers. They are specifically designed for Off–Line and dc–to–dc converter applications offering the designer a cost effective solution with minimal external components. These integrated circuits feature an oscillator, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.
? 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
? Input Undervoltage Lockout with Hysteresis
? Low Startup and Operating Current
? Direct Interface with Motorola SENSEFET Products
