  • The NCV898032 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 microprocessor compatible input pin.
  • Features
  • Peak Current Mode Control with Internal Slope Compensation - LED PWM Dimming Capable
  • 0.2 V ±3 % Reference Voltage for Constant Current Loads - Accurate Current/Voltage Regulation
  • 2 MHz Fixed Frequency Operation - Facilitates Use of Lower Cost Magnetics and Filter Capacitors
  • Wide Input Voltage Range of 3.2 V to 40 V, 45 V Load Dump - Designed for Automotive Battery Operating Environment
  • Input Undervoltage Lockout (UVLO) - Works in a Wide Variety of Applications
  • Internal Soft−Start - Disables Startup in Undervoltage Conditions
  • Low Quiescent Current in Sleep Mode (< 10 µA Typical) - Very Low Off-State Current
  • Cycle−by−Cycle Current Limit Protection - Protects Against Overcurrent Conditions
  • Hiccup−Mode Overcurrent Protection (OCP) - Protects Against Overcurrent Conditions
  • Thermal Shutdown (TSD) - Thermally Protects IC
