The UC3844B and 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:

  1. Trimmed Oscillator for Precise Frequency Control
  2. Oscillator Frequency Guaranteed at 250 kHz
  3. Current Mode Operation to 500 kHz Output Switching Frequency
  4. Output dead adjustable from 50% to 70%
  5. Automatic Feed Forward Compensation
  6. Latching PWM for Cycle−By−Cycle Current Limiting
  7. Internally Trimmed Reference with Undervoltage Lockout
  8. High Current Totem Pole Output
  9. Undervoltage Lockout with Hysteresis
