UC2844BD1R2G, ШИМ контроллер связь по току 8-SOIC

Описание UC2844BD1R2G The UC2844BD1R2G is a high-performance fixed frequency current-mode Pulse Width Modulation (PWM) Controller specifically designed for off-line and DC to DC converter applications offering the designer a cost-effective solution with minimal external components. It features 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. Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cycle-by-cycle current limiting, a latch for single pulse metering and a flip-flop which blanks the output off every other oscillator cycle, allowing output deadtimes to be programmed from 50 to 70%. • Trimmed oscillator for precise frequency control • Automatic feed forward compensation • Internally trimmed reference with undervoltage lockout • High current totem pole output • Undervoltage lockout with hysteresis • Low startup and operating current Вес, г0.15
