Light Load High Efficiency, 31V, Buck Regulator NR110E series General Descriptions The NR110E series is buck regulator ICs integrates High-side power MOSFET. The feature increasing efficiency at light loads allows the device to be used in the energy-saving applications. With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used. The ICs have protection functions such as Over-Current Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD). An adjustable Soft-Start by an external capacitor prevents the excessive inrush current at turn-on. The ICs integrate phase compensation circuit which reduces the number of external components and simplifies the design of customer application.
