The UC3845 fixed frequency current mode controller is 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 a trimmed oscillator for precise duty cycle control, 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:

  • Fixed Frequency Current-Mode PWM Controller
  • Trimmed Oscillator Discharge Current for Precise Duty Cycle Control
  • Current Mode Operation to 500 kHz
  • Automatic Feed Forward Compensation
  • Latching PWM for Cycle−By−Cycle Current Limiting
  • Internally Trimmed Reference with Under voltage Lockout
  • High Current Totem Pole Output
  • Under voltage Lockout with Hysteresis
  • Low Startup and Operating Current 

Package Includes : 

1 x UC3845 Current Mode PWM Controller IC DIP-8 Package
