NCV8871: Non-Synchronous Boost Controller, Automotive Grade

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.

Features
  • Peak Current Mode Control with Internal Slope Compensation
  • 1.2 V 2% Reference voltage
  • Wide Input Voltage Range of 3.2 V to 40 Vdc, 45 V Load Dump
  • Input undervoltage lockout (UVLO)
  • Internal SoftStart
  • Low quiescent current in sleep mode
  • Cycle-by-cycle current limit protection
  • Hiccup-mode short-circuit protection (SCP)
  • Thermal shutdown (TSD)
Benefits
  • Good transient response over a wide input voltage and load range
  • Accurate voltage regulation
  • Works in a wide variety of applications
  • Disables start up in undervoltage conditions
  • Decreases inrush current
  • Very low off current
  • Protects against over current conditions
  • Protects against short circuit faults
  • Thermally protects IC
Applications
  • Start-Stop systems
  • SEPIC (Non-inverting Buck Boost)
  • Direct Gas Injection
End Products
  • Automotive Systems
