General Description

The NR111D is a buck converter IC that integrates the power MOSFET.

With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used.

The IC has protection functions such as Overcurrent Protection (OCP), Undervoltage Lockout (UVLO) and Thermal Shutdown (TSD).

Key Features

  • Up to 94% Efficiency Up to 68% Efficiency at Maximum at Light Load (IO = 20 mA).
  • Current mode PWM control.
  • Stable with Low ESR Ceramic Output Capacitors.
  • No External Components Required by Incorporating Phase Compensation.
  • Soft-start Function Adjustable Soft-start time with an External Capacitor.
  • External ON/OFF Function.
  • Protection Functions: Overcurrent Protection (OCP): Drooping, auto-restart Thermal Shutdown (TSD): Auto-restart Undervoltage Lockout (UVLO).
