NR111E - Buck Converter

Description

The NR110E series are buck converter ICs that integrate the power MOSFET.

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

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

Features

  • Bare Lead Frame: Pb-free (RoHS Compliant).
  • Up to 94% Efficiency Up to 68% Efficiency at Maximum at Light Load (VIN = 12 V, VO = 5 V, 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.
  • Enable Function.
  • Protection Functions: Overcurrent Protection (OCP): Drooping, auto-restart Ther.

31 V, Buck Converter NR110E Series Data Sheet Description The NR110E series are buck converter ICs that integrate the power MOSFET. With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used. The ICs have protection functions such as Overcurrent Protection (OCP), Undervoltage Lockout (UVLO) and Thermal Shutdown (TSD). An adjustable Soft-start by an external capacitor prevents the excessive inrush current in startup. The feature increasing efficiency at light loads allows the device to be used in the energy-saving applications. The ICs integrate phase compensation circuit which reduces the number of external components and simplifies the design of customer application. The IC has the enable function by the EN pin that turns the regulator on or off.
