NR110E - SANKEN

NR110E Light Load High Efficiency Buck Regulator

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), Un.
