NR117K Datasheet (SANKEN) - Buck Converter

NR117K, Buck Converter

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.
