  • The NCV8871 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, hiccup-mode short-circuit protection and thermal shutdown. Additional features include low quiescent current sleep mode and externally-synchronizable switching frequency.
  • 特性
  • Peak Current Mode Control with Internal Slope Compensation - Good transient response over a wide input voltage and load range
  • 1.2 V 2% Reference voltage - Accurate voltage regulation
  • Wide Input Voltage Range of 3.2 V to 40 Vdc, 45 V Load Dump - Works in a wide variety of applications
  • Input undervoltage lockout (UVLO) - Disables start up in undervoltage conditions
  • Internal SoftStart - Decreases inrush current
  • Low quiescent current in sleep mode - Very low off current
  • Cycle-by-cycle current limit protection - Protects against over current conditions
  • Hiccup-mode short-circuit protection (SCP) - Protects against short circuit faults
  • Thermal shutdown (TSD) - Thermally protects IC
