General 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).

Key Features

  • Bare Lead Frame: Pb-free (RoHS Compliant).
