  • The NCV8873 is an adjustable output non-synchronous boost controller which drives an external N-channel MOSFET. The device uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver. Protection features include internally-set soft-start, undervoltage lockout, cycle-by-cycle current limiting and thermal shutdown. Additional features include low quiescent current sleep mode and externally-synchronizable switching frequency.
  • Features
  • Peak Current Mode Control with Internal Slope Compensation - LED PWM dimming capable
  • 0.2 V 2% Reference Voltage for Constant Current Loads - Good transient response over a wide input voltage and load range
  • Wide Input Voltage Range of 3.2 V to 45 V - Accurate current/voltage regulation
  • Input Undervoltage Lockout - Works in a wide variety of applications
  • Internal Soft Start - Disables startup in undervoltage conditions
  • Low Quiescent Current in Sleep Mode - Decreases inrush current
  • Cycle by Cycle Current Limit Protection - Very low off current
  • Hiccup Mode Overcurrent Protection - Protects against over current conditions
  • Thermal Shutdown - Thermally protects IC
