Overview
31 V, Buck Converter NR111D Data Sheet 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).
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 IC integrates phase compensation circuit which reduces the number of external components and simplifies the design of customer application.
The IC has the EN pin that turns the regulator on or off, and achieves low power consumption requirements.
The package of NR111D is the DIP8.
