UC2844BAC規(guī)格書詳情
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 temperature compensated 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
? Pb?Free Packages are Available
