1.5 A, 31 V, 30 kHz, Buck Converter NR117K Data Sheet Description The NR117K is 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 the overcurrent protection, undervoltage lockout, and thermal shutdown. 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.
