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), Under
voltage 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. The package of NR110E series is the eSOIC8 with an exposed thermal pad on the back side.
