  • The NCV898031 is an adjustable output non-synchronous 2 MHz SEPIC/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 enable pin.
  • Features
  • 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
  • 2 MHz Fixed Frequency Operation - Superior transient response, smaller size filtering components, fundamental frequency above the AM band
  • Wide Input Voltage Range of 3.2 V to 40 V, 45 V Load Dump - Works in a wide variety of applications
  • Input Undervoltage Lockout (UVLO) - Disables start up in undervoltage conditions
  • Internal Soft-Start - Decreases inrush current during startup
  • Low Quiescent Current in Sleep Mode - Very low off-state current consumption
  • 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
