  • The NCV8852 is an adjustable-output non-synchronous buck controller which drives an external P-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 internal soft-start, undervoltage lockout, cycle-by-cycle current limit, hiccup-mode overcurrent protection, hiccup-mode short-circuit protection. Additional features include programmable switching frequency, 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 range
  • 0.8 V 2% Reference Voltage - Accurate voltage regulation
  • Wide Input Voltage Range of 3.1 V to 36 Vdc, 44 V Load Dump - Works in a wide variety of applications
  • Input Undervoltage Lockout (UVLO) - Disables start-up in undervoltage conditions
  • Internal Soft-Start - Lowers inrush current and avoids output overshoot during start-up
  • Low Quiescent Current in Sleep Mode - Very low sleep current
  • Programmable Fixed Frequency 170 kHz to 500 kHz - Allows for design flexibility
  • External Clock Synchronization up to 600 kHz - Allows for frequency synchronization and spread spectrum operation
  • Cycle-by-cycle Current Limit Protection (CL) - Protects against over current conditions
  • Hiccup-mode Short-Circuit Protection (SCP) - Protects against short circuit faults
  • Thermal Shurdown (TSD) - Thermally protects the IC
  • 100% Duty Cycle Operation - Operation at low conversion ratios
