The UC3842/UC3843/UC3844/UC3845 are fixed frequencycurrent-mode PWM controller. They are specially designed for Off-Line and DC to DC converter applications with minimum external components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator and a high current totempole output for driving a Power MOSFET. The UC3842 and UC3844 have UVLO thresholds of 16V (on) and 10V (off). The UC3843 and UC3845 are 8.5V(on) and 7.9V (off). The UC3842 and UC3843 can operate within 100% duty cycle. The UC3844 and UC3845 can operate with 50% duty cycle. RoboticsBD

Features:

  1. Optimized for OFF-LINE and DC to DC converters
  2. Low Start-Up Current 1mA
  3. Automatic Feed Forward Compensation
  4. Pulse-by-pulse current limiting
  5. Enhanced load response characteristics
  6. Under-voltage lockout with hysteresis
  7. Double pulse suppression
  8. High current totem pole output
  9. Internally trimmed bandgap reference
