Additional preview pages of the NR117K datasheet.

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.

Current mode PWM control.
Stable with Low ESR Ceramic Output Capacitors.
No External Components Required by Incorporating Phase Compensation.
Soft-Start Function Adjustable Soft-Start time with an External Capacitor.
External ON/OFF Function.
Frequency: 30 kHz (EMI considered).
Protection Functions:.
Overcur.
