UC3843BN CURRENT MODE PWM IC SMD SOP-8

The UC3843BN is a high-performance current mode PWM controller IC, designed for efficient power regulation in switch mode power supplies (SMPS), DC-DC converters, and solar inverters. With fast response time, fixed frequency operation, and optimized duty cycle control, it ensures high efficiency and stability in energy-critical applications.

The SMD SOP-8 package allows for compact and efficient PCB designs, offering better thermal performance and space-saving advantages. Its built-in undervoltage lockout (UVLO), short-circuit protection, and leading-edge blanking enhance the safety and reliability of power circuits, making it an ideal choice for solar inverters.

Features

  • 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.
  • Direct Interface with ON Semiconductor SENSEFET™ Products.
  • Pb−Free Packages are Available.
