UC3844D規(guī)格書詳情
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
